I'm using the echo-canceller + preprocessor, I'd really like to improve performance here: - I would like to use ADI's FFT, but it's limited to powers of 2, is it safe to enable "Round ps_size down to the nearest power of two" in the preproc ? can we...

...b_celp.c, because this compiler will not allow variable declarations in the midst of executable code. I fixed this by bracketing this code block: line 410: { /* Added */ spx_word16_t *exc16_alias = (spx_word16_t*)st->exc; --26 more lines, then-- ol_gain = SHL32(EXTEND32(compute_rms16(exc16_alias, st->frameSize)),SIG_SHIFT); #ifdef EPIC_48K } #endif } /* Added */ 2: The decoder is broken. Running the Male.wav test file, I get all zeros out for the first 5 seconds, then 8 samples ranging from -2 to 2, and then all 0001 samples to the end of the file. I got...

Hi everyone, I've recently done some major internal changes in Speex aimed at reducing RAM (by nearly a factor of 2!) and improving quality of the fixed-point. In doing so, I might have accidently broken a few things. I'd like to hear feedback on the current svn code to make sure I fix any regression before the next release. I'm already aware that --enable-vorbis-psy is broken and
