* Flip (by making buf[i] -> buf[size-i-1]) two buffers: {sp,gain}_block. ThisVitor Sessak2008-08-06
| | | | | | needs duplicating a few loops, but now the code is clearer. Originally committed as revision 14634 to svn://svn.ffmpeg.org/ffmpeg/trunk

* Cosmetics: remove braces and useless newlineVitor Sessak2008-07-28
| | | | Originally committed as revision 14448 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Change the way the input is passed to do_hybrid_filter(). Before, in[0] wasVitor Sessak2008-07-28
| | | | | | | the oldest input sample passed and in[n-1] was the latest. Now it is the contrary. This allows making backward_filter() somewhat simpler. Originally committed as revision 14447 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove RA288Context.output buffer. This buffer is just RA288Context.sbVitor Sessak2008-07-28
| | | | | | | | backwards (output[i] == sb[N-i], where N is the buffer length). This makes the code slower, this will be fixed in my next commit. Originally committed as revision 14446 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Add a few comments pointing to the G.728 specificationVitor Sessak2008-07-27
| | | | Originally committed as revision 14444 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove the history buffer from the context. It can easily be evaluatedVitor Sessak2008-07-27
| | | | | | from the lhist buffer. Originally committed as revision 14443 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Rename two context buffers: pr{1,2} -> {sp,gain}_lpc. Also add a few doxyVitor Sessak2008-07-27
| | | | | | comments. Originally committed as revision 14437 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove st1 and st2 temporary buffers in backward_filter() and use insteadVitor Sessak2008-07-27
| | | | | | | | 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
* Change slightly the meaning of RA288Context.phase. ThisVitor Sessak2008-07-27
| | | | | | | allows to remove two intermediary buffers and avoid a few memcpy's. Originally committed as revision 14432 to svn://svn.ffmpeg.org/ffmpeg/trunk
