Otherwise the FPU will handle - * the error and return the result infinity (INF) (10.0 / 0.0 = INF) without - * throwing an error to the application. - * The same applies to a division by INF that either raises an exception - * (FPE enabled) or returns 0.0 (FPE disabled). - * Normally (as with C-programs), Floating-point exceptions (FPE) are DISABLED - * on program startup (at least with Intel CPUs), but for some strange reasons - * they are ENABLED in pascal (both delphi and FPC) by default. - * Many libs operating with floating-point values rely heavily on the C-specific - * behaviour. So using them in delphi is a ticking time-bomb because sooner or - * later they will crash because of an FPE (this problem occurs massively - * in OpenGL-based libs like projectM). In contrast to this no error will occur - * if the lib is linked to a C-program. - * - * Further info on FPUs: - * For x86 and x86_64 CPUs we have to consider two FPU instruction sets. - * The math co-processor i387 (aka 8087 or x87) set introduced with the i386 - * and SSE (Streaming SIMD Extensions) introduced with the Pentium3. - * Both of them have separate control-registers (x87: FPUControlWord, SSE: MXCSR) - * to control FPEs. Either has (among others) 6bits to enable/disable several - * exception types (Invalid,Denormalized,Zero,Overflow,Underflow,Precision). - * Those exception-types must all be masked (=1) to get the default C behaviour. - * The control-registers can be set with the asm-ops FLDCW (x87) and LDMXCSR (SSE). - * Instead of using assembler code, we can use Set8087CW() provided by delphi and - * FPC to set the x87 control-word. FPC also provides SetSSECSR() for SSE's MXCSR. - * Note that both Delphi and FPC enable FPEs (e.g. for div-by-zero) on program - * startup but only FPC enables FPEs (especially div-by-zero) for SSE too. - * So we have to mask FPEs for x87 in Delphi and FPC and for SSE in FPC only. - * FPC and Delphi both provide a SetExceptionMask() for control of the FPE - * mask. SetExceptionMask() sets the masks for x87 in Delphi and for x87 and SSE - * in FPC (seems as if Delphi [2005] is not SSE aware). So SetExceptionMask() - * is what we need and it even is plattform and CPU independent. - * - * Pascal OpenGL headers (like the Delphi standard ones or JEDI-SDL headers) - * already call Set8087CW() to disable FPEs but due to some bugs in the JEDI-SDL - * headers they do not work properly with FPC. I already patched them, so they - * work at least until they are updated the next time. In addition Set8086CW() - * does not suffice to disable FPEs because the SSE FPEs are not disabled by this. - * FPEs with SSE are a big problem with some libs because many linux distributions - * optimize code for SSE or Pentium3 (for example: int(INF) which convert the - * double value "infinity" to an integer might be automatically optimized by - * using SSE's CVTSD2SI instruction). So SSE FPEs must be turned off in any case - * to make USDX portable. - * - * Summary: - * Call this function on initialization to make sure FPEs are turned off. - * It will solve a lot of errors with FPEs in external libs. - *) -procedure DisableFloatingPointExceptions(); -begin - (* - // We will use SetExceptionMask() instead of Set8087CW()/SetSSECSR(). - // Note: Leave these lines for documentation purposes just in case - // SetExceptionMask() does not work anymore (due to bugs in FPC etc.). - {$IF Defined(CPU386) or Defined(CPUI386) or Defined(CPUX86_64)} - Set8087CW($133F); - {$IFEND} - {$IF Defined(FPC)} - if (has_sse_support) then - SetSSECSR($1F80); - {$IFEND} - *) - - // disable all of the six FPEs (x87 and SSE) to be compatible with C/C++ and - // other libs which rely on the standard FPU behaviour (no div-by-zero FPE anymore). - SetExceptionMask([exInvalidOp, exDenormalized, exZeroDivide, - exOverflow, exUnderflow, exPrecision]); -end; - -function StringReplaceW(text : WideString; search, rep: WideChar):WideString; -var - iPos : integer; -// sTemp : WideString; -begin -(* - result := text; - iPos := Pos(search, result); - while (iPos > 0) do - begin - sTemp := copy(result, iPos + length(search), length(result)); - result := copy(result, 1, iPos - 1) + rep + sTEmp; - iPos := Pos(search, result); - end; -*) - result := text; - - if search = rep then - exit; - - for iPos := 0 to length( result ) - 1 do - begin - if result[ iPos ] = search then - result[ iPos ] := rep; - end; -end; - -function AdaptFilePaths( const aPath : widestring ): widestring; -begin - result := StringReplaceW( aPath, '\', PathDelim );//, [rfReplaceAll] ); -end; - - -{$IFNDEF MSWINDOWS} -procedure ZeroMemory( Destination: Pointer; Length: DWORD ); -begin - FillChar( Destination^, Length, 0 ); -end; - -function MakeLong(A, B: Word): Longint; -begin - Result := (LongInt(B) shl 16) + A; -end; - -(* -function QueryPerformanceCounter(lpPerformanceCount:TLARGEINTEGER):Bool; - - // From http://en.wikipedia.org/wiki/RDTSC - function RDTSC: Int64; register; - asm - rdtsc - end; - -begin - // Use clock_gettime here maybe ... from libc - lpPerformanceCount := RDTSC(); - result := true; -end; - -function QueryPerformanceFrequency(lpFrequency:TLARGEINTEGER):Bool; -begin - lpFrequency := 0; - result := true; -end; -*) -{$ENDIF} - -// Checks if a regular files or directory with the given name exists. -// The comparison is case insensitive. -function FileExistsInsensitive(var FileName: string): boolean; -var - FilePath, LocalFileName: string; - SearchInfo: TSearchRec; -begin -{$IFDEF LINUX} // eddie: Changed FPC to LINUX: Windows and Mac OS X dont have case sensitive file systems - // speed up standard case - if FileExists(FileName) then - begin - Result := true; - exit; - end; - - Result := false; - - FilePath := ExtractFilePath(FileName); - if (FindFirst(FilePath+'*', faAnyFile, SearchInfo) = 0) then - begin - LocalFileName := ExtractFileName(FileName); - repeat - if (AnsiSameText(LocalFileName, SearchInfo.Name)) then - begin - FileName := FilePath + SearchInfo.Name; - Result := true; - break; - end; - until (FindNext(SearchInfo) <> 0); - end; - FindClose(SearchInfo); -{$ELSE} - Result := FileExists(FileName); -{$ENDIF} -end; - - -{$IFDEF Unix} - // include resource-file info (stored in the constant array "resources") - {$I ../resource.inc} -{$ENDIF} - -function GetResourceStream(const aName, aType: string): TStream; -{$IFDEF Unix} -var - ResIndex: integer; - Filename: string; -{$ENDIF} -begin - Result := nil; - - {$IFDEF Unix} - for ResIndex := 0 to High(resources) do - begin - if (resources[ResIndex][0] = aName ) and - (resources[ResIndex][1] = aType ) then - begin - try - Filename := ResourcesPath + resources[ResIndex][2]; - Result := TFileStream.Create(Filename, fmOpenRead); - except - Log.LogError('Failed to open: "'+ resources[ResIndex][2] +'"', 'GetResourceStream'); - end; - exit; - end; - end; - {$ELSE} - try - Result := TResourceStream.Create(HInstance, aName , PChar(aType)); - except - Log.LogError('Invalid resource: "'+ aType + ':' + aName +'"', 'GetResourceStream'); - end; - {$ENDIF} -end; - -// +++++++++++++++++++++ helpers for RWOpsFromStream() +++++++++++++++ - function SdlStreamSeek( context : PSDL_RWops; offset : Integer; whence : Integer ) : integer; cdecl; - var - stream : TStream; - origin : Word; - begin - stream := TStream( context.unknown ); - if ( stream = nil ) then - raise EInvalidContainer.Create( 'SDLStreamSeek on nil' ); - case whence of - 0 : origin := soFromBeginning; // Offset is from the beginning of the resource.

It is specifically designed +// for geometric calculations within R3 (affine vector space) +// and R4 (homogeneous vector space). +// +// Note: The terms 'affine' or 'affine coordinates' are not really correct here +// because an 'affine transformation' describes generally a transformation which leads +// to a uniquely solvable system of equations and has nothing to do with the dimensionality +// of a vector. One could use 'projective coordinates' but this is also not really correct +// and since I haven't found a better name (or even any correct one), 'affine' is as good +// as any other one. +// +// Identifiers containing no dimensionality (like affine or homogeneous) +// and no datatype (integer..extended) are supposed as R4 representation +// with 'single' floating point type (examples are TVector, TMatrix, +// and TQuaternion). The default data type is 'single' ('GLFloat' for OpenGL) +// and used in all routines (except conversions and trigonometric functions). +// +// Routines with an open array as argument can either take Func([1,2,3,4,..]) or Func(Vect). +// The latter is prefered, since no extra stack operations is required. +// Note: Be careful while passing open array elements! If you pass more elements +// than there's room in the result the behaviour will be unpredictable. +// +// If not otherwise stated, all angles are given in radians +// (instead of degrees). Use RadToDeg or DegToRad to convert between them. +// +// Geometry.pas was assembled from different sources (like GraphicGems) +// and relevant books or based on self written code, respectivly. +// +// Note: Some aspects need to be considered when using Delphi and pure +// assembler code. Delphi ensures that the direction flag is always +// cleared while entering a function and expects it cleared on return. +// This is in particular important in routines with (CPU) string commands (MOVSD etc.) +// The registers EDI, ESI and EBX (as well as the stack management +// registers EBP and ESP) must not be changed! EAX, ECX and EDX are +// freely available and mostly used for parameter. +// +// Version 2.5 +// last change : 04. January 2000 +// +// (c) Copyright 1999, Dipl. Ing.

Thanks again. - - Revision 1.2 2004/08/14 22:54:30 savage - Updated so that Library name defines are correctly defined for MacOS X. - - Revision 1.1 2004/03/30 21:53:54 savage - Moved to it's own folder. - - Revision 1.4 2004/02/20 17:09:55 savage - Code tidied up in gl, glu and glut, while extensions in glext.pas are now loaded using SDL_GL_GetProcAddress, thus making it more cross-platform compatible, but now more tied to SDL. - - Revision 1.3 2004/02/14 00:23:39 savage - As UNIX is defined in jedi-sdl.inc this will be used to check linux compatability as well. Units have been changed to reflect this change. - - Revision 1.2 2004/02/14 00:09:18 savage - Changed uses to now make use of moduleloader.pas rather than dllfuncs.pas - - Revision 1.1 2004/02/05 00:08:19 savage - Module 1.0 release - - Revision 1.6 2003/06/02 12:32:12 savage - Modified Sources to avoid warnings with Delphi by moving CVS Logging to the top of the header files.

May contains bugs, but I hope not. - - Revision 1.1 2004/03/30 21:53:54 savage - Moved to it's own folder. - - Revision 1.6 2004/03/28 00:28:43 savage - Fixed some glSecondaryColor definitions... - - Revision 1.5 2004/02/20 17:18:16 savage - Forgot to prefix function pointer with @ for FPC and other Pascal compilers. - - Revision 1.4 2004/02/20 17:09:55 savage - Code tidied up in gl, glu and glut, while extensions in glext.pas are now loaded using SDL_GL_GetProcAddress, thus making it more cross-platform compatible, but now more tied to SDL. - - Revision 1.3 2004/02/14 22:36:29 savage - Fixed inconsistencies of using LoadLibrary and LoadModule. - Now all units make use of LoadModule rather than LoadLibrary and other dynamic proc procedures. - - Revision 1.2 2004/02/14 00:09:19 savage - Changed uses to now make use of moduleloader.pas rather than dllfuncs.pas - - Revision 1.1 2004/02/05 00:08:19 savage - Module 1.0 release - - Revision 1.7 2003/06/02 12:32:13 savage - Modified Sources to avoid warnings with Delphi by moving CVS Logging to the top of the header files.

postcard of your city to my above address. -=============================================================================================== -!!! All parts of this code which are not finished or not conforming exactly to - the XmlSpec are marked with three exclamation marks - --!- Parts where the parser may be able to detect errors in the document's syntax are - marked with the dash-exlamation mark-dash sequence. -=============================================================================================== -Terminology: ------------- -- Start: Start of a buffer part -- Final: End (last character) of a buffer part -- DTD: Document Type Definition -- DTDc: Document Type Declaration -- XMLSpec: The current W3C XML Recommendation (version 1.0 as of 1998-02-10), Chapter No. -- Cur*: Fields concerning the "Current" part passed back by the "Scan" method -=============================================================================================== -Scanning the XML document -------------------------- -- Create TXmlParser Instance MyXml := TXmlParser.Create; -- Load XML Document MyXml.LoadFromFile (Filename); -- Start Scanning MyXml.StartScan; -- Scan Loop WHILE MyXml.Scan DO -- Test for Part Type CASE MyXml.CurPartType OF -- Handle Parts ... : ;;; -- Handle Parts ... : ;;; -- Handle Parts ... : ;;; - END; -- Destroy MyXml.Free; -=============================================================================================== -Loading the XML document ------------------------- -You can load the XML document from a file with the "LoadFromFile" method. -It is beyond the scope of this parser to perform HTTP or FTP accesses. If you want your -application to handle such requests (URLs), you can load the XML via HTTP or FTP or whatever -protocol and hand over the data buffer using the "LoadFromBuffer" or "SetBuffer" method. -"LoadFromBuffer" loads the internal buffer of TXmlParser with the given null-terminated -string, thereby creating a copy of that buffer. -"SetBuffer" just takes the pointer to another buffer, which means that the given -buffer pointer must be valid while the document is accessed via TXmlParser. -=============================================================================================== -Encodings: ----------- -This XML parser kind of "understands" the following encodings: -- UTF-8 -- ISO-8859-1 -- Windows-1252 - -Any flavor of multi-byte characters (and this includes UTF-16) is not supported. Sorry. - -Every string which has to be passed to the application passes the virtual method -"TranslateEncoding" which translates the string from the current encoding (stored in -"CurEncoding") into the encoding the application wishes to receive. -The "TranslateEncoding" method that is built into TXmlParser assumes that the application -wants to receive Windows ANSI (Windows-1252, about the same as ISO-8859-1) and is able -to convert UTF-8 and ISO-8859-1 encodings. -For other source and target encodings, you will have to override "TranslateEncoding". -=============================================================================================== -Buffer Handling ---------------- -- The document must be loaded completely into a piece of RAM -- All character positions are referenced by PChar pointers -- The TXmlParser instance can either "own" the buffer itself (then, FBufferSize is > 0) - or reference the buffer of another instance or object (then, FBuffersize is 0 and - FBuffer is not NIL) -- The Property DocBuffer passes back a pointer to the first byte of the document. If there - is no document stored (FBuffer is NIL), the DocBuffer returns a pointer to a NULL character. -=============================================================================================== -Whitespace Handling -------------------- -The TXmlParser property "PackSpaces" determines how Whitespace is returned in Text Content: -While PackSpaces is true, all leading and trailing whitespace characters are trimmed of, all -Whitespace is converted to Space #x20 characters and contiguous Whitespace characters are -compressed to one. -If the "Scan" method reports a ptContent part, the application can get the original text -with all whitespace characters by extracting the characters from "CurStart" to "CurFinal". -If the application detects an xml:space attribute, it can set "PackSpaces" accordingly or -use CurStart/CurFinal. -Please note that TXmlParser does _not_ normalize Line Breaks to single LineFeed characters -as the XmlSpec requires (XmlSpec 2.11). -The xml:space attribute is not handled by TXmlParser. This is on behalf of the application. -=============================================================================================== -Non-XML-Conforming ------------------- -TXmlParser does not conform 100 % exactly to the XmlSpec: -- UTF-16 is not supported (XmlSpec 2.2) - (Workaround: Convert UTF-16 to UTF-8 and hand the buffer over to TXmlParser) -- As the parser only works with single byte strings, all Unicode characters > 255 - can currently not be handled correctly. -- Line breaks are not normalized to single Linefeed #x0A characters (XmlSpec 2.11) - (Workaround: The Application can access the text contents on its own [CurStart, CurFinal], - thereby applying every normalization it wishes to) -- The attribute value normalization does not work exactly as defined in the - Second Edition of the XML 1.0 specification. -- See also the code parts marked with three consecutive exclamation marks. These are - parts which are not finished in the current code release. - -This list may be incomplete, so it may grow if I get to know any other points. -As work on the parser proceeds, this list may also shrink. -=============================================================================================== -Things Todo ------------ -- Introduce a new event/callback which is called when there is an unresolvable - entity or character reference -- Support Unicode -- Use Streams instead of reading the whole XML into memory -=============================================================================================== -Change History, Version numbers -------------------------------- -The Date is given in ISO Year-Month-Day (YYYY-MM-DD) order. -Versions are counted from 1.0.0 beginning with the version from 2000-03-16. -Unreleased versions don't get a version number. - -Date Author Version Changes ------------------------------------------------------------------------------------------------ -2000-03-16 HeySt 1.0.0 Start -2000-03-28 HeySt 1.0.1 Initial Publishing of TXmlParser on the destructor.de Web Site -2000-03-30 HeySt 1.0.2 TXmlParser.AnalyzeCData: Call "TranslateEncoding" for CurContent -2000-03-31 HeySt 1.0.3 Deleted the StrPosE function (was not needed anyway) -2000-04-04 HeySt 1.0.4 TDtdElementRec modified: Start/Final for all Elements; - Should be backwards compatible. - AnalyzeDtdc: Set CurPartType to ptDtdc -2000-04-23 HeySt 1.0.5 New class TObjectList.

All parts of this code which are not finished or not conforming exactly to + the XmlSpec are marked with three exclamation marks + +-!- Parts where the parser may be able to detect errors in the document's syntax are + marked with the dash-exlamation mark-dash sequence. +=============================================================================================== +Terminology: +------------ +- Start: Start of a buffer part +- Final: End (last character) of a buffer part +- DTD: Document Type Definition +- DTDc: Document Type Declaration +- XMLSpec: The current W3C XML Recommendation (version 1.0 as of 1998-02-10), Chapter No. +- Cur*: Fields concerning the "Current" part passed back by the "Scan" method +=============================================================================================== +Scanning the XML document +------------------------- +- Create TXmlParser Instance MyXml := TXmlParser.Create; +- Load XML Document MyXml.LoadFromFile (Filename); +- Start Scanning MyXml.StartScan; +- Scan Loop WHILE MyXml.Scan DO +- Test for Part Type CASE MyXml.CurPartType OF +- Handle Parts ... : ;;; +- Handle Parts ... : ;;; +- Handle Parts ... : ;;; + END; +- Destroy MyXml.Free; +=============================================================================================== +Loading the XML document +------------------------ +You can load the XML document from a file with the "LoadFromFile" method. +It is beyond the scope of this parser to perform HTTP or FTP accesses. If you want your +application to handle such requests (URLs), you can load the XML via HTTP or FTP or whatever +protocol and hand over the data buffer using the "LoadFromBuffer" or "SetBuffer" method. +"LoadFromBuffer" loads the internal buffer of TXmlParser with the given null-terminated +string, thereby creating a copy of that buffer. +"SetBuffer" just takes the pointer to another buffer, which means that the given +buffer pointer must be valid while the document is accessed via TXmlParser. +=============================================================================================== +Encodings: +---------- +This XML parser kind of "understands" the following encodings: +- UTF-8 +- ISO-8859-1 +- Windows-1252 + +Any flavor of multi-byte characters (and this includes UTF-16) is not supported. Sorry. + +Every string which has to be passed to the application passes the virtual method +"TranslateEncoding" which translates the string from the current encoding (stored in +"CurEncoding") into the encoding the application wishes to receive. +The "TranslateEncoding" method that is built into TXmlParser assumes that the application +wants to receive Windows ANSI (Windows-1252, about the same as ISO-8859-1) and is able +to convert UTF-8 and ISO-8859-1 encodings. +For other source and target encodings, you will have to override "TranslateEncoding". +=============================================================================================== +Buffer Handling +--------------- +- The document must be loaded completely into a piece of RAM +- All character positions are referenced by PChar pointers +- The TXmlParser instance can either "own" the buffer itself (then, FBufferSize is > 0) + or reference the buffer of another instance or object (then, FBuffersize is 0 and + FBuffer is not NIL) +- The Property DocBuffer passes back a pointer to the first byte of the document. If there + is no document stored (FBuffer is NIL), the DocBuffer returns a pointer to a NULL character. +=============================================================================================== +Whitespace Handling +------------------- +The TXmlParser property "PackSpaces" determines how Whitespace is returned in Text Content: +While PackSpaces is true, all leading and trailing whitespace characters are trimmed of, all +Whitespace is converted to Space #x20 characters and contiguous Whitespace characters are +compressed to one. +If the "Scan" method reports a ptContent part, the application can get the original text +with all whitespace characters by extracting the characters from "CurStart" to "CurFinal". +If the application detects an xml:space attribute, it can set "PackSpaces" accordingly or +use CurStart/CurFinal. +Please note that TXmlParser does _not_ normalize Line Breaks to single LineFeed characters +as the XmlSpec requires (XmlSpec 2.11). +The xml:space attribute is not handled by TXmlParser. This is on behalf of the application. +=============================================================================================== +Non-XML-Conforming +------------------ +TXmlParser does not conform 100 % exactly to the XmlSpec: +- UTF-16 is not supported (XmlSpec 2.2) + (Workaround: Convert UTF-16 to UTF-8 and hand the buffer over to TXmlParser) +- As the parser only works with single byte strings, all Unicode characters > 255 + can currently not be handled correctly. +- Line breaks are not normalized to single Linefeed #x0A characters (XmlSpec 2.11) + (Workaround: The Application can access the text contents on its own [CurStart, CurFinal], + thereby applying every normalization it wishes to) +- The attribute value normalization does not work exactly as defined in the + Second Edition of the XML 1.0 specification. +- See also the code parts marked with three consecutive exclamation marks. These are + parts which are not finished in the current code release. + +This list may be incomplete, so it may grow if I get to know any other points. +As work on the parser proceeds, this list may also shrink. +=============================================================================================== +Things Todo +----------- +- Introduce a new event/callback which is called when there is an unresolvable + entity or character reference +- Support Unicode +- Use Streams instead of reading the whole XML into memory +=============================================================================================== +Change History, Version numbers +------------------------------- +The Date is given in ISO Year-Month-Day (YYYY-MM-DD) order. +Versions are counted from 1.0.0 beginning with the version from 2000-03-16. +Unreleased versions don't get a version number. + +Date Author Version Changes +----------------------------------------------------------------------------------------------- +2000-03-16 HeySt 1.0.0 Start +2000-03-28 HeySt 1.0.1 Initial Publishing of TXmlParser on the destructor.de Web Site +2000-03-30 HeySt 1.0.2 TXmlParser.AnalyzeCData: Call "TranslateEncoding" for CurContent +2000-03-31 HeySt 1.0.3 Deleted the StrPosE function (was not needed anyway) +2000-04-04 HeySt 1.0.4 TDtdElementRec modified: Start/Final for all Elements; + Should be backwards compatible. + AnalyzeDtdc: Set CurPartType to ptDtdc +2000-04-23 HeySt 1.0.5 New class TObjectList.

MAKEFILE -WRITEWAV\ WAVE writer example - WRITEWAV.C - MAKEFILE - - -What's the point? -================= -BASS is an audio library for use in Windows and MacOSX software. Its -purpose is to provide the most powerful and efficient (yet easy to use), -sample, stream, MOD music, and recording functions. All in a tiny DLL, -under 100KB in size. - -See the documentation for descriptions of all the BASS functions. You -should also look at the included example program source-codes for some -examples of how to use BASS in your own programs. - - -Requirements -============ -Win32 version -------------- -BASS requires DirectX 3 or above for output. BASS does not require that a -soundcard with DirectSound/DirectSound3D hardware accelerated drivers is -installed, but it does improve performance if there is one. BASS also takes -advantage of MMX, which improves the performance of the MOD music playback. - -MacOSX version --------------- -OSX 10.3 or above is recommended. BASS uses CoreAudio for output, so there -are no special library/driver requirements. BASS supports both PowerPC and -Intel Macs. - - -Main Features -============= -* Samples - supports WAV/AIFF/MP3/MP2/MP1/OGG and custom generated samples - -* Sample streams - stream any sample data in 8/16/32 bit, with both "push" and "pull" systems - -* File streams - MP3/MP2/MP1/OGG/WAV/AIFF file streaming - -* Internet file streaming - stream files from the internet, including Shout/Icecast - -* User file streaming - stream files from anywhere using any delivery method - -* Multi-channel streaming - support for more than plain stereo, including multi-channel OGG/WAV/AIFF files - -* MOD music - uses the same engine as XMPlay = best accuracy, speed, and quality - -* MO3 music - MP3/OGG compressed MOD music - -* Add-on system - support for more formats is available via add-ons (aka plugins) - -* Multiple outputs - simultaneously use multiple soundcards, and move channels between them - -* Recording - flexible recording system, with support for multiple devices - -* Decode without playback - streams and MOD musics can be outputted in any way you want - -* Speaker assignment - assign streams and MOD musics to specific speakers - -* High precision synchronization - synchronize events in your software to the streams and MOD musics - -* DirectX 8 effects - chorus/compressor/distortion/echo/flanger/gargle/parameq/reverb - -* User defined DSP functions - custom effects may be applied to musics and streams - -* 32 bit floating-point decoding and processing - floating-point stream/music decoding, DSP, FX, and recording - -* 3D sound - play samples/streams/musics in any 3D position, with EAX support - -* Small - BASS is under 100KB (on Windows), so won't bloat your distribution - - -Using BASS -========== -There is no guarantee that all future BASS versions will be compatible -with all previous versions, so your program should use BASS_GetVersion -to check the version that is loaded. This also means that you should -put the BASS module in the same directory as your executable (not just -somewhere in the path), to avoid the possibility of a wrong version being -loaded. - -If you are updating your software from a previous BASS version, then -you should check the "History" section (below), to see if any of the -functions that you are using have been affected by a change. - -Win32 version -------------- -C/C++, Visual Basic, Delphi and MASM APIs are provided, to use BASS with -another language you'll first have to convert the header file. Or, as a -last resort, you could use LoadLibrary and GetProcAddress. - -The downside is that you have to manually import each function that you -use, with the GetProcAddress function. But it has been made a lot simpler -to import BASS this way by the use of the BASSDEF #define. Here's a small -example: - -#define BASSDEF(f) (WINAPI *f) // define the functions as pointers -#include "bass.h" -... -HINSTANCE bass=LoadLibrary("BASS.DLL"); // load BASS -BASS_Init=GetProcAddress(bass,"BASS_Init"); // get BASS_Init -BASS_Init(-1,44100,0,hWnd,NULL); // call BASS_Init - -To use BASS with Borland C++ Builder, you'll first have to create a -Borland C++ Builder import library for it. This is done by using the -IMPLIB tool that comes with Borland C++ Builder. Simply execute this: - - IMPLIB BASSBCB.LIB BASS.DLL - -... and then use BASSBCB.LIB in your projects to import BASS. - -To use BASS with LCC-Win32, you'll first have to create a compatible -import library for it. This is done by using the PEDUMP and BUILDLIB -tools that come with LCC-Win32. Run these 2 commands: - - PEDUMP /EXP BASS.LIB > BASSLCC.EXP - BUILDLIB BASSLCC.EXP BASSLCC.LIB - -... and then use BASSLCC.LIB in your projects to import BASS. - -For the BASS functions that return strings (char*), VB users should use -the VBStrFromAnsiPtr function to convert the returned pointer into a VB -string. - -MacOSX version --------------- -A separate "LIB" file is not required for OSX. Using XCode, you can simply -add the DYLIB file to the project. Or using a makefile, you can build your -programs like this, for example: - - gcc yoursource -L. -lbass -o yourprog - -The LIBBASS.DYLIB file must be put in the same directory as the executable -(it can't just be somewhere in the path). See the example makefiles. - -LIBBASS.DYLIB is a universal binary, with support for both PowerPC and -Intel Macs. If you want PowerPC-only or Intel-only versions, the included -makefile can create them for you, by typing "make ppc" or "make i386". It -will also process any BASS add-ons placed in the same directory. - - -Latest Version -============== -The latest version of BASS can always be found at the BASS website: - - www.un4seen.com - - -Licence -======= -BASS is free for non-commercial use. If you are a non-commercial entity -(eg. an individual) and you are not charging for your product, and the -product has no other commercial purpose, then you can use BASS in it -for free. If you wish to use BASS in commercial products, then please -also see the next section. - -TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, BASS IS PROVIDED -"AS IS", WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, -INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY -AND/OR FITNESS FOR A PARTICULAR PURPOSE. THE AUTHORS SHALL NOT BE HELD -LIABLE FOR ANY DAMAGE THAT MAY RESULT FROM THE USE OF BASS. YOU USE -BASS ENTIRELY AT YOUR OWN RISK. - -Usage of BASS indicates that you agree to the above conditions. - -All trademarks and other registered names contained in the BASS -package are the property of their respective owners. - -Commercial licensing --------------------- -BASS is available for use in your commercial products. The licence -types available are as follows: - -SHAREWARE: Allows the usage of BASS in an unlimited number of your -shareware products, which must sell for no more than 40 Euros each. -If you are an individual (not a corporation) making and selling your -own software (and its price is within the limit), this is the licence -for you. - -SINGLE COMMERCIAL: Allows the usage of BASS in a single commercial -product. - -UNLIMITED COMMERCIAL: Allows the usage of BASS in an unlimited number -of your commercial products. This licence is on a per site basis. So -if your company has two sites that use BASS, then two licences are -required. - -Please note the products must be end-user products, eg. not components -used by other products. - -These licences only cover your own software, not the publishing of -other's software. If you publish other's software, its developers (or -the software itself) will need to be licensed to use BASS. - -These licences are on a per-platform basis, with reductions available -when licensing for both platforms. In all cases there are no royalties -to pay, and you can use future BASS updates without further cost. One -licence covers one person or entity and is not transferable. - -These licences do not allow reselling/sublicensing of BASS. For example, -if a product is a development system, the users of said product are not -licensed to use BASS in their productions; they will need their own -licences. - -If the standard licences do not meet your requirements, or if you have -any questions, please get in touch (email: bass@un4seen.com). - -Visit the BASS website for the latest pricing: - - www.un4seen.com - -MP3 ---- -MP3 technology is patented, and Thomson license the use of their and -Fraunhofer's patents. The inclusion of an MP3 decoder (eg. BASS) in a -commercial product requires an MP3 patent licence. Contact Thomson for -details: - - www.mp3licensing.com - -Alternatively, the "MP3-FREE" BASS version does not include its own MP3 -decoder but instead makes use of the operating system's already licensed -decoder. - -NOTE: When using the OS's MP3 decoder, BASS still does the file handling - so all the usual features are still supported, including streaming, - tag reading, pre-scanning, gapless playback, etc... - - -History -======= -These are the major (and not so major) changes at each version stage. -There are of course bug fixes and other little improvements made along -the way too! To make upgrading simpler, all functions affected by a -change to the BASS interface are listed. - -2.4 - 2/4/2008 --------------- -* "Push" streaming - STREAMPROC_PUSH (BASS_StreamCreate "proc") - BASS_StreamPutData -

+================= +BASS is an audio library for use in Windows and MacOSX software. Its +purpose is to provide the most powerful and efficient (yet easy to use), +sample, stream, MOD music, and recording functions. All in a tiny DLL, +under 100KB in size. + +See the documentation for descriptions of all the BASS functions. You +should also look at the included example program source-codes for some +examples of how to use BASS in your own programs. + + +Requirements +============ +Win32 version +------------- +BASS requires DirectX 3 or above for output. BASS does not require that a +soundcard with DirectSound/DirectSound3D hardware accelerated drivers is +installed, but it does improve performance if there is one. BASS also takes +advantage of MMX, which improves the performance of the MOD music playback. + +MacOSX version +-------------- +OSX 10.3 or above is recommended. BASS uses CoreAudio for output, so there +are no special library/driver requirements. BASS supports both PowerPC and +Intel Macs. + + +Main Features +============= +* Samples + supports WAV/AIFF/MP3/MP2/MP1/OGG and custom generated samples + +* Sample streams + stream any sample data in 8/16/32 bit, with both "push" and "pull" systems + +* File streams + MP3/MP2/MP1/OGG/WAV/AIFF file streaming + +* Internet file streaming + stream files from the internet, including Shout/Icecast + +* User file streaming + stream files from anywhere using any delivery method + +* Multi-channel streaming + support for more than plain stereo, including multi-channel OGG/WAV/AIFF files + +* MOD music + uses the same engine as XMPlay = best accuracy, speed, and quality + +* MO3 music + MP3/OGG compressed MOD music + +* Add-on system + support for more formats is available via add-ons (aka plugins) + +* Multiple outputs + simultaneously use multiple soundcards, and move channels between them + +* Recording + flexible recording system, with support for multiple devices + +* Decode without playback + streams and MOD musics can be outputted in any way you want + +* Speaker assignment + assign streams and MOD musics to specific speakers + +* High precision synchronization + synchronize events in your software to the streams and MOD musics + +* DirectX 8 effects + chorus/compressor/distortion/echo/flanger/gargle/parameq/reverb + +* User defined DSP functions + custom effects may be applied to musics and streams + +* 32 bit floating-point decoding and processing + floating-point stream/music decoding, DSP, FX, and recording + +* 3D sound + play samples/streams/musics in any 3D position, with EAX support + +* Small + BASS is under 100KB (on Windows), so won't bloat your distribution + + +Using BASS +========== +There is no guarantee that all future BASS versions will be compatible +with all previous versions, so your program should use BASS_GetVersion +to check the version that is loaded. This also means that you should +put the BASS module in the same directory as your executable (not just +somewhere in the path), to avoid the possibility of a wrong version being +loaded. + +If you are updating your software from a previous BASS version, then +you should check the "History" section (below), to see if any of the +functions that you are using have been affected by a change. + +Win32 version +------------- +C/C++, Visual Basic, Delphi and MASM APIs are provided, to use BASS with +another language you'll first have to convert the header file. Or, as a +last resort, you could use LoadLibrary and GetProcAddress. + +The downside is that you have to manually import each function that you +use, with the GetProcAddress function. But it has been made a lot simpler +to import BASS this way by the use of the BASSDEF #define. Here's a small +example: + +#define BASSDEF(f) (WINAPI *f) // define the functions as pointers +#include "bass.h" +... +HINSTANCE bass=LoadLibrary("BASS.DLL"); // load BASS +BASS_Init=GetProcAddress(bass,"BASS_Init"); // get BASS_Init +BASS_Init(-1,44100,0,hWnd,NULL); // call BASS_Init + +To use BASS with Borland C++ Builder, you'll first have to create a +Borland C++ Builder import library for it. This is done by using the +IMPLIB tool that comes with Borland C++ Builder. Simply execute this: + + IMPLIB BASSBCB.LIB BASS.DLL + +... and then use BASSBCB.LIB in your projects to import BASS. + +To use BASS with LCC-Win32, you'll first have to create a compatible +import library for it. This is done by using the PEDUMP and BUILDLIB +tools that come with LCC-Win32. Run these 2 commands: + + PEDUMP /EXP BASS.LIB > BASSLCC.EXP + BUILDLIB BASSLCC.EXP BASSLCC.LIB + +... and then use BASSLCC.LIB in your projects to import BASS. + +For the BASS functions that return strings (char*), VB users should use +the VBStrFromAnsiPtr function to convert the returned pointer into a VB +string. + +MacOSX version +-------------- +A separate "LIB" file is not required for OSX. Using XCode, you can simply +add the DYLIB file to the project. Or using a makefile, you can build your +programs like this, for example: + + gcc yoursource -L. -lbass -o yourprog + +The LIBBASS.DYLIB file must be put in the same directory as the executable +(it can't just be somewhere in the path). See the example makefiles. + +LIBBASS.DYLIB is a universal binary, with support for both PowerPC and +Intel Macs. If you want PowerPC-only or Intel-only versions, the included +makefile can create them for you, by typing "make ppc" or "make i386". It +will also process any BASS add-ons placed in the same directory. + + +Latest Version +============== +The latest version of BASS can always be found at the BASS website: + + www.un4seen.com + + +Licence +======= +BASS is free for non-commercial use. If you are a non-commercial entity +(eg. an individual) and you are not charging for your product, and the +product has no other commercial purpose, then you can use BASS in it +for free. If you wish to use BASS in commercial products, then please +also see the next section. + +TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, BASS IS PROVIDED +"AS IS", WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, +INCLUDING BUT NOT LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY +AND/OR FITNESS FOR A PARTICULAR PURPOSE. THE AUTHORS SHALL NOT BE HELD +LIABLE FOR ANY DAMAGE THAT MAY RESULT FROM THE USE OF BASS. YOU USE +BASS ENTIRELY AT YOUR OWN RISK. + +Usage of BASS indicates that you agree to the above conditions. + +All trademarks and other registered names contained in the BASS +package are the property of their respective owners. + +Commercial licensing +-------------------- +BASS is available for use in your commercial products. The licence +types available are as follows: + +SHAREWARE: Allows the usage of BASS in an unlimited number of your +shareware products, which must sell for no more than 40 Euros each. +If you are an individual (not a corporation) making and selling your +own software (and its price is within the limit), this is the licence +for you. + +SINGLE COMMERCIAL: Allows the usage of BASS in a single commercial +product. + +UNLIMITED COMMERCIAL: Allows the usage of BASS in an unlimited number +of your commercial products. This licence is on a per site basis. So +if your company has two sites that use BASS, then two licences are +required. + +Please note the products must be end-user products, eg. not components +used by other products. + +These licences only cover your own software, not the publishing of +other's software. If you publish other's software, its developers (or +the software itself) will need to be licensed to use BASS. + +These licences are on a per-platform basis, with reductions available +when licensing for both platforms. In all cases there are no royalties +to pay, and you can use future BASS updates without further cost. One +licence covers one person or entity and is not transferable. + +These licences do not allow reselling/sublicensing of BASS. For example, +if a product is a development system, the users of said product are not +licensed to use BASS in their productions; they will need their own +licences. + +If the standard licences do not meet your requirements, or if you have +any questions, please get in touch (email: bass@un4seen.com). + +Visit the BASS website for the latest pricing: + + www.un4seen.com + +MP3 +--- +MP3 technology is patented, and Thomson license the use of their and +Fraunhofer's patents. The inclusion of an MP3 decoder (eg. BASS) in a +commercial product requires an MP3 patent licence. Contact Thomson for +details: + + www.mp3licensing.com + +Alternatively, the "MP3-FREE" BASS version does not include its own MP3 +decoder but instead makes use of the operating system's already licensed +decoder. + +NOTE: When using the OS's MP3 decoder, BASS still does the file handling + so all the usual features are still supported, including streaming, + tag reading, pre-scanning, gapless playback, etc... + + +History +======= +These are the major (and not so major) changes at each version stage. +There are of course bug fixes and other little improvements made along +the way too!
