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 b...

...ve the time, can you please check on my test code below and see where i could be having problems with. (this is the handler that processes captured audio) LRESULT CRecordSound::OnSoundData(WPARAM wParam, LPARAM lParam) { LPWAVEHDR lpHdr = (LPWAVEHDR) lParam; int buflen = lpHdr->dwBufferLength; //160 float * buf = toFloat(lpHdr->lpData, buflen); // Encode some audio int nRet = enc.encode(buf, buflen); unsigned char *compressed = enc.getOutput(); int clen = enc.getOutputLength(); int speechDetected = enc.getSpeechDetected();...

Hello, I know my question has been asked before because I spent the last week searching the web for how to use Speex in combination with WaveIn/WaveOut and I ran into a few posts, but none of them answer the question. There is still a lot of confusion how to use WaveIn/WaveOut and Speex by junior developers such as myself. Even after examining code for SpeexDec and SpeexEnc, I cannot get clear

Thank you for such a quick response. The only reason I started with Char buffers is because WaveIn and WaveOut on Windows XP accept/emit WAVEHDR structures, which store audio data in LPSTR, which is Char*. typedef struct { LPSTR lpData; DWORD dwBufferLength; ... } WAVEHDR; When I was going from Char to float and back looked very wrong to me as well, but I was just not sure (and still am) how to translate the Char* audio stream generated by WaveIn to a format that can be understood by Speex. Would using speex_decode_int and speex_encode_int instead...
