+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
+

+		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

+
+		function:CSoundFile::~CSoundFile()

+-> 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

+
+date = 05-feb-2001 [Markus Fick]
+-> file: fastmix.cpp
+         where: macros + filter order
+         what: [modify] changed filter order to 8 instead of 10
