What’s the easiest way to record like 4-12 hours of low-information audio (a ticking clock basically) most compactly?

You can get 12 hrs of ticking clock to fit in ~1 kB by playing a 00:00:01 recording with this setting on

Heh, I’m actually building a mechanical clock and want to DFT the uneven ticking to investigate geartrain friction. 12h= one cycle through all states of geartrain I think.https://twitter.com/vgr/status/1302385904040833024 …

Oh, so you just need the timing information? You might look at ditching the audio and using a peak detector and only record time stamps (or time deltas). A cheap mic into something like an arduino which spits out the timing via a serial port

Yes I was thinking of that too... though the raw signal would have harmonics and crap, so it’s not just the peak times
