Sonaura
Mix your own soundscape for sleep, focus & calm
What it does
Sonaura is a calming soundscape app for sleep, focus, and relaxation. Instead of playing one static sound, you layer up to 14 sounds from a library of 250+ — rain, fire, ocean, brown noise, ASMR — and save your favorite mixes. With Journeys, you can chain saved mixes into a timed sequence: 30 minutes of rain, then brown noise until morning. Works fully offline, no ads, no dark patterns — just a simple, distraction-free way to build your own sound environment.

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
