120ms worth

Posted by Joe Murphy Jr on December 10, 2011 at 14:11:58:
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.
