Has anyone tried recording full-duplex audio on their iPAQ and had any
problems with dropouts or small gaps in the recording, every 1 or 2
seconds?

Is this due to inefficient code, hardware limitations, or what?

see the code posted in

Is it possible to programatically scan a WAV file for drop-outs
(completely empty segments) and fill them in by interpolating the
samples directly before & after?

Yes, although it may be difficult to distinguish between drop-outs and
segments that are intentionally silent.

This will probably not be a satisfactory approach if more than one or two
samples are "missing".

True, especially for short quick sounds that would be completely
missing.

I am not sure but I am getting dropouts trying to record full-duplex
(while playing back a different mono sound with headphones) on my
Pocket PC (iPAQ 3650) using Smart Device Framework 1.1 (opennetcf.org)
