*exploding brain* LTspice can import and export simulation waveforms as... Wave files! Yes, .wav, the usually audio format! I guess this is actually super useful if you're simulating audio circuitry

Indeed, the manual warns you that media players might object to weird formats; and I think I'd you handed me such a file without explanation I might be confused and object too But as weird as it may be, it feels like it's still a good use of the formathttps://twitter.com/pepijndevos/status/1263439620638945281?s=19 …

In similar creative repurposing of audio equipment: there's specifications for recording laser shows on 8-track, and later ADAT tapes.

Why? Well, you need to continuously control 5-ish channels for the laser: X, Y, R, G, B. You might want separate intensity or time code. And, normally you want synchronised music as well, and it leaves you two channels for that

Recorders were cheap, and many could do high sample rates. So people repurposed them and bypassed the AC coupling capacitors

Perhaps the most confusing thing about this is that the analogue connection lasers use (ILDA) is DB-25 based, and there's a DB-25 based standard for 8 way analogue multicores recorders often supported, but.. the pinouts are wildly different!

This is why OpenLase uses JACK to transport laser data (in sync with audio). The data is basically "audio-shaped". The wav thing reminds me of a CTF level I built once, where I gave them a UDP packet in 100BASE-TX recorded as a 500MHz sample rate wav file.
