Support for compressed audio messages?

Hello!

Having in mind freakwan already supports tiny images, I'm curious if freakwan could support highly compressed/optimized audio messages? I think it could make it interesting for audio-based uses, for instance walkie-talk like?

Normally this request may sound outlandish since audio is significantly larger than text, but [EnCodec](https://ai.honu.io/papers/encodec/samples.html) seems to push the envelope as even 1.5 kbps is quite comprehensible.

Sorry I haven't yet fully understood the bandwidth and time on air calculations to know how silly is this question, still quite excited about this project.
