Void FM

I’ve never been a good sleeper. Ambient sound is the only thing that helps, and every app I tried was either too busy, looped the same clip until I hated it, or wanted a subscription.

So I built my own. Void FM is a little shortwave receiver: five bands, twenty-two channels, all generated live so nothing ever repeats. You can tune it by hand or let it scan. Most nights I just pick a channel and stop paying attention.

It’s an excuse to make the sounds I actually wanted to sleep to. A datacenter at 3am. Rain on concrete. A numbers station reading a message that isn’t for you. No files, no loops — just the Web Audio API doing the work.

I still put it on every night. Try it if you have trouble sleeping too.
