Ronald, I suggest we take this discussion off the list after this post. I don't see any problems with your code. However, I can make a few suggestions: 1) If you replace the lines: pSpeexHdr->lpData = (char*)pSound; pSpeexHdr->dwBufferLength = decodedSamples * sizeof(short); with: pSpeexHdr->lpData = lpHdr->lpData; pSpeexHdr->dwBufferLength = lpHdr->dwBufferLength; does it sound right? If not, your problem is not with the encoding or decoding. 2) Try checking the error state of the classes after each method call, and before you try t...

...h 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 encoding and decoding of the audio and doesn't have any kind of container support (lik...
