I friend has a web radio station. It has been on the air 24/7 for
several
years. He's been having random problems with dropouts and something
that seem to me like some sort of digital feedback.

The dropouts seem to me to be a buffering issue. I've found that
most of the time if I cut out the dead air no data seems to be lost.
I'm thinking this may be a channel capacity problem with his ISP.

I don't have any idea what's causing the "digital feedback" issue.
Here's a link to a clip of the feedback/echo/reverb thing.

In this case the "feedback" lasted about two and half minutes.
I've included the onset, the end, and my friend's apology to the
audience.

Can anyone here provide any insight into potential causes and solutions?

Sounds to me like part of the same bandwidth issue. After a dropout or
series of them, the music gets time-crunched (sped up without altering
pitch by chopping bits out) to get back into sync with real time. Same
as happens on a Skype call with slow internet. Could the ISP be
throttling the speed?
Too many NetFlix users in his area.

A friend from Bell Labs sent me this suggestion:
~~
Could "buffer bloat" be the culprit?
https://en.wikipedia.org/wiki/Bufferbloat.

I can see how that applies to dropouts or stutter but don't quite understand
the echo.
Anyway, I agree that it's likely related to an upload overload with his ISP,
and if so there's little he can do to address the problem. :-(
