".....padding the audio with zeros....." = digital delay
How many zeros do you need to add to delay the audio by 120m/s?
Follow Ups:
I believe you mean " ms " (milliseconds), as the " / " between " m/s " means " per " (eg, miles/second, meters/second, etc) and delay time in Home Theater applications is normally expressed in milliseconds ( ms ). If you meant something else by m/s , perhaps you could type out the abbreviation.
But to answer your question, the DSP will output all zeros as a buffer, for a user specified amount of time (in your case, 120 milliseconds), before the audio stream it received is sent to the D-A converter. If you'd like to know how many actual zeros are in 120ms, you need to also specify the sampling rate and the bit depth.
Again, I am asking you to point me to relevant discussion of delay induced jitter so that I can read up on this subject.
