For various reason, one audio receiving from network and
other thru air.

Yes delay estimation is required as the delay is not known upfront.
In addition to re-sampling stretching also required.

Hi Ben,

this is a vague description of the task. What is the reason that signal
1 is ahead of signal 2? What apps do you want to use, resp. do those
apps support plain alsa or jack or pulseaudio?

Perhaps a simple delay is what you are looking for, but maybe you need
resampling.

Regards,
Ralf
