Robert Swain	341b28c0d2	Zero 'idx' for each iteration of the coupling gain loop and as it is only used within this loop, we can move its declaration there too.

Based on a patch by Alex Converse (alex converse gmail com) Originally committed as revision 15364 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Robert Swain	408992bae2	Operands of '+' are not necessarily evaluated in order so r15311 was pointless. Splitting the assignment onto two lines should resolve the order issue. Originally committed as revision 15313 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Alex Converse	19645d742e	Correct order of parsing for pulse scalefactor band and offset to match the specification. Patch by Alex Converse (alex converse gmail com) Originally committed as revision 15311 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Patch by Alex Converse (alex converse gmail com) Fixes another issue pertaining to issue632 Originally committed as revision 15303 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Robert Swain	febcbd65fa	Correct pulse amplitude application - a negative or 0 coefficient implies the pulse is subtracted, else it is added. Also avoid a divide by 0. Based on a patch by Alex Converse (alex converse gmail com) Fixes part of issue632 Originally committed as revision 15294 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Vitor Sessak	1775c7fac6	Multiply table by -1. This avoid doing this calculation (that was introduced in my last commit) in real time. Originally committed as revision 15195 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Robert Swain	f4fae46e67	Remove unnecessary portion of a condition. This fixes issue607 and avoids another unintended bug where channel coupling could have been run on an SCE. Originally committed as revision 15036 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Robert Swain	b0f5852a13	Use ff_imdct_half() and vector_fmul_window() for IMDCT and windowing. Reduce buffer sizes accordingly. This produces a ~10% overall decoding perfomance improvement. Originally committed as revision 14908 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Robert Swain	db38c38624	Whitespace cosmetics after the last commit Originally committed as revision 14907 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
