Show HN: See your computer's audio output on a real-time piano

[ecstrema]

I built this for 2 usecases:

- When listening to music, I very often what is currently being played. Be it a the current chord, a short lick, etc. - When transcribing, I don't like the workflow of extracting a complete audio and transforming it midi, so I thought having this helper on the side, but still do most of the work by myself could be very useful.

Disclaimer: the app is limited by the model's performance. Basic-Pitch is a relatively small model which runs super well on consumer laptops. I get around 50FPS of inference on my laptop (AMD Radeon 780M).

Of course, this wouldn't be possible without:

- Tauri: https://tauri.app/ - Basic Pitch: https://github.com/spotify/basic-pitch - ONNX: https://onnx.ai/
