[Freeswitch-users] Manipulating audio streams at sample level

[Michael Jerris]

why are they out of sync in the first place?
You can't solve echo by adding delay.  This needs to be solved in a
different way.  if someone is being picked up by 2 microphones, your going
to get a stereo effect, is that what you mean?  if so, you'd want to use
microphones that won't pick up the same person twice.
