search for: byteswritten

...the mic, I send it to Speex in a Char buffer. It looks something like this: Encode(char* inBuffer, DWORD bufferLength) ... float* input = new float[frameSize]; ZeroMemory(input, frameSize); ... for( ) { input[..] = inBuffer[..]; } ... speex_encode(enc_state, input, &bits); int bytesWritten = speex_bits_nbytes(&bits); speex_bits_write(&bits, encBuffer, bytesWritten); Then, my decoding routine accepts the char buffer that was encoded with Speex: Decode(char* encBuffer, DWORD bufferLength) ... float* output = new float[frameSize]; ... speex_bits_read_from(&amp...

...bBytes, &bytesRead, NULL); totalBytesRead += bytesRead; speex_bits_read_from(&bits, cbits, nbBytes); speex_decode(state, &bits, out); for( i=0; i <FRAME_SIZE; i++) buf[i] = (char)out[i]; // write to file WriteFile(file2, buf, FRAME_SIZE, &bytesWritten, NULL); totalBytesWritten+= bytesWritten; } I am using wave api for capturing and playing back sound. Please guide me in this problem. Regards, Ali Naqi Shaheen, <p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To...
