Hello The st->zeta pointer isn't freed in the speex_preprocess_state_destroy() function of the preprocess.c file (alloced in line 167). It's in Speex 1.1.4 by the way. I'm trying to make the denoiser work with my application and has got reasonable noise reduction after applying the denoiser. I, however, haven't been able to find any information of what the...

Bjoern, As far as I understand it, AGC keeps the volume level of the speech elements (i.e. gain) stable no matter how quiet or loud the input becomes- Tom At 10:53 AM 3/28/2004, Bjoern Rasmussen wrote: >Hello > >The st->zeta pointer isn't freed in the speex_preprocess_state_destroy() >function of the preprocess.c file (alloced in line 167).

Thanks for letting me know. I'll change that for the next release (in the mean time, the fix is obvious). In case you're interested, I'm currently working on a reverberati...

another optimization you can do for packing bits together... the original one is : ------------------------------------------------------------------------------------------------------------- void speex_bits_pack(SpeexBits *bits, int data, int nbBits) { int i; unsigned int d=data; if (bits->bytePtr+((nbBits+bits->bitPtr)>>3) >= bits->buf_size) { //remain
