hi guys, i am trying to develop an application having a capability to detect voice activity in voice stream and then record only portion of this stream which contains the activity. i went through these steps. 1. Captured voice through Waveform Functions of Windows Multimedia API 2. Started Speex Preprocessing liberary 3. Turned on preprocessor by calling speex_preprocess_state_init and
