...r, the VAD done by speex_preprocess() works much better. You will also get better results if you enable the denoiser, I think. peex_preprocess_ctl(preprocess, SPEEX_PREPROCESS_SET_DENOISE, &denoise_enabled); speex_preprocess_ctl(preprocess, SPEEX_PREPROCESS_SET_VAD, &vad_enabled); speechDetected = speex_preprocess(preprocess, floatbuf, NULL); Hope this helps, Tom Abhishek Parakh (abhishekp@ee.iitm.ac.in) wrote: > > Hello. > > I have generated a dll out of speex-1.1.4 using VC++6.

...rt int[], buflen is multiple of frame size // (there is a getFrameSize() method for both classes) // Encode some audio tgAudioEncoder enc(16000); // you could do 8000 instead enc.enableVAD(1); enc.encode(buf, buflen); unsigned char *compressed = enc.getOutput(); int clen = enc.getOutputLen(); int speechDetected = enc.getSpeechDetected(); // Decode it tgAudioDecoder dec(16000); int decodedSamples = dec.decode(compressed, clen); memcpy(buf, dec.getOutput(), decodedSamples * sizeof(short int)); Anyway, that's the basic idea. I don't think it could get much easier. :) Now, this is only raw enco...
