It could be, but it would be very difficult - you would have to buffer a
large amount of data ahead of time, calculate the average audio drift
over this period, and then compensate the audio.  If you make the
compensation period too small, you will have to make too many small
corrections, and it will not sound good.

If you do get a capture engine written up with this core, let me know -
I would like to use it.
