I've installed (free) RealProducer to encode voice quality audio off
the radio and my backyard bird microphones, pretty much 24/7
recording into 3-hour files (which come out about 12MB each).

Unlike real encoder which preceded it years ago, it seems to
crap out at random, at least on my Dell Inspiron 1200, recording
zero signal except for cross-talk level suggestions of the
input. It does this mabye once in twenty hours or so.

It appears not to be a dirty contact problem, though it's
fixed by unplugging the 3.5mm stereo input and plugging it
back in, for it happens identically on another computer ;
and is not responsive to aggressive cleaning with DeOxit,
which normally fixes everything connection-wise.

Oddly, going to a Behringer UCA202 USB audio device instead
has sort of the opposite problem, going to full-volume audio
at random, and clipping.

Maybe the common component here is the real producer program.

I'm running it at real-time priority (it comes apparently
at normal priority, which makes it drop data under load).
And run it from shell scripts (automatic command line).

I like the *.rm audio file sizes, so would like to stick with it.

Perhaps somebody else has had and solved this problem?

The Behringer UCA-202 problem is undoubtedly a shifted bit
that comes up.

http://home.att.net/~rhhardina/UCA202.ra

is a 30-second span when it happens. I'm listening to the same input
on headphones and it's fine, and encoded it at the same time on another
computer and it's fine.

If I turn the input volume way down, the audio comes back, but very
rapidly overflows again as the shifted bit hits the MSB position.

The other encoded correctly sees very weak audio with the volume down.

I wonder how generic USB audio devices work, to help assign blame
among encoder, system (XP) and RealProducer 11.0 Basic.

Oh, well, it's back to the onboard line in jack, which runs many more
hours between its unexplained failures.
