Icecast - Dec 2020 - How to improve stream quality with sources on jittery/high latency connections?

Hello all:

I am a novice in setting up Icecast servers. I wanted to understand if the
community has guidance on how to improve stream quality when sources are on
unreliable connections.

Specifically, I have a source that broadcasts on jittery cellular connection.
The connection does have sufficient bandwidth, but does have high latency and
jitter (that is sometimes the latency is high other times low and this changes
in an unpredictable way). Unfortunatelly, I can?t use a different connection for
the source.

The issues manifests with stream dropouts or occassionally with the stream ?fast
forwarding?. The same source on a high quality network connection doesn?t have
theses issues, so I am fairly certain that that connection itself is the
culprit.

I am willing to trade off stream latency for reliablity. That is, I would be
happy to introduce say a minute (or more) of latency into the stream to
compensate for the jittery connection. However, I am uncertain which paramteres
to change in the configuration to accomplish this.

I am also open to other solutions for this problem or links to guides that
people have written on how to deal with this.

The current source configuration is macOS with Audio Hijack for the broadcast.
Running the latest Icecast on my own server.

Thank you for you input and guidance,

Martin
