libmodplug v0.7 - A library for decoding MOD-like music formats.
Based on the ModPlug sound engine by Olivier Lapicque <olivierl@jps.net>
Ported to Unix by Kenton Varda <temporal@gauge3d.org>
Additional modifications by Markus Fick <marf@gmx.net> and
Adam Goode <adam@evdebs.org>
Placed in the public domain in October, 2001
All the documentation needed can be found in the comments in modplug.h.
This library should be perfectly accessible from C, although it is written
in C++. Just #include <modplug.h> to use it, and link against
libmodplug.so.
This library has been known to compile fine in Windows using MinGW32 (A
GCC-based compiler). Windows is not yet officially supported, however.
(With about half an hour of hacking, any decent programmer should be able
to convince WinAmp to play mods using this library. ;) )
I need a maintainer for this. I have too many other projects I am working
on, and ModPlug has dropped low on the list. If you would like to be the
new maintainer, please e-mail me at <temporal@gauge3d.org> and tell me why
you think you would be the right person for the job. :)

changes:
date = 09-feb-2001 [Markus Fick]
-> file: fastmix.cpp
where: spline creation, spline macros
what: added unity gain clamp code, added Quantizer_Bits(shift) preprocessor constants
where: fir creation, fir macros
what: - removed x<pi/2 condition in coef creation
- added quantizer_bits(shift) preprocessor constants
- set default quantizer bits to 15 instead 14 (scale now 32768 instead 16384)
there should not occure any overflows during fir response calculation because
of the symmetric form of filter and the position of the negative fir coefs
- changed final volume calculation for 16bit samples (quality enhancement)
date = 08-feb-2001 [Markus Fick]
-> file: sndmix.cpp
where: function ReadNote()
what: modified behaviour of modplug so that interpolation is only deactivated if
a) the user selects "no interpolation"
b) linear interpolation is set and speed incr. > 0xff00
=> if spline or fir is active then we use always interpolation
-> file: fastmix.cpp
where: spline macros
what: changed spline macros to use precalculated tables (way faster)
where: file
what: - implemented spline table precalculator
- changed fir precalculator + macros (for higher quality and clearer source)
- added some comments and documentation
comment:
- preprocessor constant: SPLINE_FRACBITS
) controls quality/memory usage
range is [4..14] inclusive
4 = low quality, low memory usage
14 = highest quality, highest memory usage (1L<<14)*4*2 bytes
- preprocessor constant: WFIR_FRACBITS
) controls quality/memory usage
range is [4..12] inclusive
4 = low quality, low mu
12 = highest quality, highest memory usage ((1L<<(12+1))+1)*8*2 bytes
date = 07-feb-2001 [Markus Fick]
-> file: fastmix.cpp
where: spline macros
what: fixed error in coef calculation
date = 07-feb-2001 [Markus Fick]
-> file: sndfile.h
where: class definition of soundfile
what: removed InitFIR + DoneFIR function prototypes
-> file: sndfile.cpp
function:CSoundFile::CSoundFile()
what: [modify] removed call to CSoundFile::InitFIRMixer( )
function:CSoundFile::~CSoundFile()
what: [modify] removed call to CSoundFile::DoneFIRMixer( )
-> file: fastmix.cpp
where: spline macros
what: changed formula + added some guard bits to calculation
where: fir macros + implementation
what: - moved CSoundfile::FIR funtions to CzFIR (single instance sfir)
- changed fir macros to support CzFIR class
date = 06-feb-2001 [Markus Fick]
-> file: fastmix.cpp
where: macros
what: - removed fir filter with coef interpolation
- add spline interpolation
RM: now modplug->select( SPLINE ) selects spline and
modplug->select( POLYPHASE ) selects 8tap fir filter
date = 05-feb-2001 [Markus Fick]
-> file: fastmix.cpp
where: macros + filter order
what: [modify] changed filter order to 8 instead of 10
-> file: fastmix.cpp
what: new macros+switch for fir-interpolator with coef interpolation
date = 04-feb-2001 [Markus Fick]
-> file: sndfile.h
where: class CSoundFile (bottom)
what: [add] methods for FIR mixer support
1. int InitFIRInterpolator( );
2. int DoneFIRInterpolator( );
-> file: sndfile.cpp
function:CSoundFile::CSoundFile()
what: [modify] add call to CSoundFile::InitFIRMixer( )
function:CSoundFile::~CSoundFile()
what: [modify] add call to CSoundFile::DoneFIRMixer( )
-> file: fastmix.cpp
new include: <math.h>
why: need it for fir-coef calculation
new function: CSoundFile::InitFIRMixer( ) // initializes fir filter lookup (if necessary)
new function: CSoundFile::DoneFIRMixer( ) // decrements ReferenceCounter (for static vars) and deinitializes fir struct (if possible).

#define FIRLEN 9 // number(-1) of multiplications per sample
#define FIRCUT 0.90f // cutoff of filter
#define MIXNDX_FIRMIXERSRC 0x20 // src-type for firfilter

static float nFirFC = FIRCUT; // cutoff (normalized to pi/2)
static int nFirCpw = (1L<<FIRCPWBN); // number of precalculted filter lines
static int nFirUsers = 0; // reference counter
new macros:
#define SNDMIX_GETMONOVOL8FIRFILTER
#define SNDMIX_GETMONOVOL16FIRFILTER
#define SNDMIX_GETSTEREOVOL8FIRFILTER
#define SNDMIX_GETSTEREOVOL16FIRFILTER
