Vitor Sessak	b26d320583	Add a few comments pointing to the G.728 specification Originally committed as revision 14444 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	854ce441c3	Remove the history buffer from the context. It can easily be evaluated from the lhist buffer. Originally committed as revision 14443 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	0143ec2a7e	Rename two context buffers: pr{1,2} -> {sp,gain}_lpc. Also add a few doxy comments. Originally committed as revision 14437 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	59da0390dc	Remove st1 and st2 temporary buffers in backward_filter() and use instead RA288Context.pr{1,2}. Note that the pr{1,2} buffers are one unity smaller than the st{1,2} buffers. My guess is that the original coder decided to add one to the array sizes "just to be sure". Originally committed as revision 14435 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	3df136d438	Change slightly the meaning of RA288Context.phase. This allows to remove two intermediary buffers and avoid a few memcpy's. Originally committed as revision 14432 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	f42eb5715d	Remove st1 and st2 variables from context, since they could be just local vars Originally committed as revision 14421 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	272d258ab9	Rename st{1,2}{a,b} context variables to more meaningful names: {sp,gain}_{rec,hist} Originally committed as revision 14420 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
