be sure to start the audio source before attempting capture. when a digital audio source (such as dv or aes/ebu) is selected before the audio is turned on, the osprey-540 is unable to determine the sampling rate. the sampling rate is a measure of the amount of binary data needed to reproduce the audio being capture. if the audio source is not available, the osprey-540 cannot determine the format of the incoming audio.

    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 sounds slower or faster than normal when it is played back. should this occur, stop and restart capturing audio.

    the default digital audio sampling rate is 48 khz. some common sampling rates are:

    1 48 khz (typical for sdi)

    2 44.1 khz

    3 32 khz or 48 khz for dv sources
