For any kind of capture with computation, you need to use the DS concept of read and capture positions. Basically, allocate a DS capture buffer of at least 2 * framesize * sizeof(short), preferably 4 * framesize or so. Keep calling pDSCaptureBuffer->GetCurrentPosition(&dwCapturePosition, &dwReadPosition) When dwReadPosition has changed enough since the last processed frame that there's a whole frame ready, lock the region from dwLastFrameReadPosition to dwReadPosition. Never lock the entire buffer, that will halt capture while you compress. Copy the locked region i...

Hello everyone I've a following problem with the speex codec. I'm developing application that is supposed to read sounds from the microphone with DirectSoundCapture. Unfortunately when I want to compress and decompress the sound buffer from DirectSound I only have jitter. Maybe you have some code samples how to compress standard DS buffers: LPDIRECTSOUND8 lpDS = NULL;
