...ser can do an excellent job of cleaning up the signal. So it seems that VAD is being done before denoising, and looking at the code for speex_preprocess(), I think this is the case. (Am I wrong?) Why not do VAD after denoising? It seems like it would be much more reliable.

...is there any speex code in place that may help enable variable speed playback ? or perhaps another open source project has some code for this ? variable speed playback for voice messaging is an attractive feature, that would be well recieved for sure ! thx for any reply, Mark Tom Harper <tharper@sightspeed.com> wrote: At 12:35 PM 10/6/2004, Matthias Granberry wrote: >There is some SSE assembly >language, but it's in GCC/AT&T syntax rather than the windows-standard >Intel syntax, so you might have to do some of your own translation to >something your compiler understa...

...curious how that number was picked (i.e. perceptual, engineering judgment, etc)? I understand you wouldn't want to adapt the denoiser when someone is talking, the question is whether a small amount of residual echo could mess it up (i.e. maybe 3 is too small?)

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 purpose of

Hi everyone, I'm currently attempting to move Speex development over to Git. Because Git is distributed, I means that anyone would be able to do development and commits without having to get write access (and I can just pull from them). There are of course other advantages, like sane handling of branches and tags, local history, ... Now, one of the disadvantages is that Git currently
