As I understand it, there are two separate ways to get VAD information from Speex: 1) Using the encoder. 2) Using speex_preprocess(). I present the following observations from an application developer's perspective. They may be wrong, in which case I would appreciate corrections. - The two VAD systems are implemented differently. - speex_preprocess()'s VAD provides more accurate

I'm finding it dificult to get the code to fit within c5x dsp, especially due to the large heap necessary for the huge allocations in nb_encoder_init and nb_decoder_init. Are the people that have this running using additonal external ram? Has anyone experimented with reducing the internal encoder/decoder stack sizes for narrow band... is there a practical minimum that is usable? Also,

Jamey, There is a previous posting in the speex archives with a link to the dsp c5x patch. Archive link: http://lists.xiph.org/pipermail/speex-dev/2004-October/002847.html Patch link: http://lists.xiph.org/pipermail/speex-dev/attachments/20041029/facb8c73/spee x-1.1.6-jeh1-0001.bin But that patch is very different (much smaller) then the dsp c5x patch at

I saw a thread in the list archives about a speex port to TI 55x DSP. Wondering how that worked out (is working out)? Also wondering if there is a source archive for it, or if the patch in the email archives is still current, or if there's been updates. Any info appreciated. Thanks Paul
