[Freeswitch-users] Manipulating audio streams at sample level

I have a scenario where I'd like to be able to manipulate audio streams
coming into FS on a sample level.

This is a 3-party SIP call where 2 parties (A and B) are in the same room but
using individual handsets. This creates an echo effect for the third
party (C) since the audio streams from A and B will arrive at her location slightly out
of sync.

So at the start of a call I want to examine the audio streams coming from A B as they come into
FS to see how out of sync they are, then add an appropriate delay to the
one that's ahead and put that delayed audio back into FS.
