Hello. I thought to make this suggestion, since I suggested it on the IRC/Discord channel, and it wasn't yet proposed.

The format is the IBM PC Speaker. It's described here: https://en.wikipedia.org/wiki/PC_speaker

An example of work with PC Speaker: https://battleofthebits.com/academy/GroupThread/19773/

A tool that can be used to make PC Speaker music: http://www.oldskool.org/pc/MONOTONE

Worth noting that Furnace lets you route PC speaker output to your real speaker... if your speaker is compatible with being driven by software. But there's not really an 'export' yet.

This format could work really well for a battle like this one!
The question is, will such a battle ever grace the great arena halls?
(and what exactly would the file format even be?)

intresting...

but we hav fsound :o :o
