50FPS inference on consumer laptop using Basic-Pitch with cpal audio capture.

Strengths

•Real-time system audio capture with cpal library in Rust backend
•Helps transcription workflow without replacing manual ear training entirely
•Automated GitHub Actions build releases for all platforms from release branch

Weaknesses

•Fundamentally wraps Spotify's Basic-Pitch model with UI layer
•Model performance limits accuracy — basic chords only, not complex arrangements

Post Description

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:
