Tested for all sample rates specified in capture_rates (8000, 11025, 16000, 22050, 24000, 32000, 44100, 48000) plus couple of others in the range from 4kHz to 192kHz, everything for stereo/mono/8/16bit. No audible popping. -- Jindrich Makovicka ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
