Thanks! > > -David You can expect that. They're all the same 16-bit signed and interleaved PCM format at this time. Samplerate is the only option for audio data itself which does have defines for the platform. It shouldn't be assumed playback and recording rates match perfectly. It shouldn't be assumed full-duplex is available. It shouldn't be assumed that if duplex is available that record and playback will match when looping (Austria Microsystems cases). I hope that clears up any questions. Mike
