the only format that the osprey-210/220 audio capture driver supports is pcm. the driver supports the following data rates:

    1 8 khz

    2 11.025 khz

    3 16 khz

    4 22.05 khz

    5 32 khz

    6 44.1 khz

    7 48 khz

    these data rates are supported in 8-bit and 16-bit, mono and stereo formats. the actual osprey-210/220 hardware supports sampling of analog audio at 32, 44.1 and 48 khz. depending on the requested audio format, the osprey-210/220 driver automatically selects the most appropriate hardware sampling rate. for example, if 22.5 khz audio is desired, the audio driver selects the 44.1 khz audio rate and down samples it to 22.05 khz.

    it should be noted that the osprey-220 does not currently dynamically readjust sampling rates while audio capture is in progress. thus audio capture should be stopped and restarted whenever the audio input port changes.

    for mono sources, the osprey-220 uses only the left audio channel. optionally, this can be configured to be the left channel or a mix of the left and right channels.

    when a capture is started before the audio source is selected, the audio may not be sampled at the correct rate. audio sampled at an incorrect rate will sound slower or faster than normal when it is played back. should this occur, stop and restart capturing audio.
