Vitor Sessak	36826ee0df	Declare temporary buffers to be only of the necessary size Originally committed as revision 14451 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	5e707c5905	Remove redundant comments Originally committed as revision 14450 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	c6ad13044a	Cosmetics: do not align with now removed next instruction Originally committed as revision 14449 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	2c46367163	Cosmetics: remove braces and useless newline Originally committed as revision 14448 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	2b356efec2	Change the way the input is passed to do_hybrid_filter(). Before, in[0] was 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	17 years ago
Vitor Sessak	aed39f6c02	Remove RA288Context.output buffer. This buffer is just RA288Context.sb 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	17 years ago
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
Vitor Sessak	efa86ebe4c	Cosmetics: remove useless parenthesis Originally committed as revision 14418 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Vitor Sessak	029e1c01b5	Give the context structure of ra288 a better name: s/Real288_internal/RA288Context/ Originally committed as revision 14413 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Vitor Sessak	a6755f8d53	Rename and comment bandwidth broadening tables (s/table1a/syn_bw_tab/, s/table2a/gain_bw_tab/). Originally committed as revision 14363 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	5e65f5df0e	Follow FFmpeg convention of returning negative values on error in eval_lpc_coeffs() Originally committed as revision 14362 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Vitor Sessak	a0cce1587b	Give windowing tables a more descriptive name (s/table1/syn_window/, s/table2/gain_window/). Originally committed as revision 14360 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Vitor Sessak	427981c7a6	Rename co() function to the much more descriptive name of do_hybrid_window(). Also change a misleading and wrong comment. Originally committed as revision 14357 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Vitor Sessak	5ab3d66fe5	Simplify co(): write constant in a more readable way Originally committed as revision 14356 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago

Vitor Sessak	0e3510a31f	Revert r14218. FFMAX is a macro, so sum = FFMAX(1, scalar_product(...)); might calculate the scalar product twice, which is slower. Originally committed as revision 14230 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
