Hej Clemens, Alfons just replied the same way which confuses me. I don't doubt you're right but I want to explain what confuses me : 32kHz,128 Samples/Frame - The delay between the actual finger snap (recorded directly to the left channel of my recording device) and the play back from the ALSA-driven-soundcard recorded to the right channel is 8ms. So is it that it takes 4ms to capture and 4ms to play it back or what could be the reason for the additional 4ms ? Best -- A l e x -- Dipl.-Ing.
