Hi all, I've spent some time working on music demixing or music source separation algorithms, which take in a mixed song and output estimates of isolated components (e.g. vocals, drums, bass, other). I took a popular PyTorch model with good performance (Open-Unmix, UMX-L weights), reimplemented the inference steps in C++, and compiled it to WebAssembly for a free client-side music demixer.

Hi HN, Last time I showed free-music-demixer, which people seemed to enjoy. It was a static website with a Javascript + WASM module to perform music demixing (or music source separation) using an AI model UMX-L (Open-Unmix) running client-side in the browser. Since then, I have overhauled the project and made several improvements: - The demixing/separation quality is higher now, since I implemented the missing post-processing step - Memory usage is lower now by performing a custom segmented inference with a streaming LSTM, which should allow larger tracks (or, dare I say,…

Hi HN, I built a simple harmonica practice app that shows real-time pitch and bending targets for each hole. It helps blues harp players visualize their technique and improve intonation. No tracking, no ads, open source (MIT). The app is available on F-Droid and GitHub. You can find more details here: https://letsbend.de Feedback welcome!

Hey HN, I'm a software engineer with a passion for playing guitar. (https://ivanhsu.co) In the software industry, we use clever plain-text syntaxes like Markdown and Mermaid to handle complex layouts. This lets us focus on the content itself and quickly produce beautifully formatted documents. Isn't sheet music and chord charts just another form of documentation in the world of music? That's why I created Cord Land https://cord.land/landing ! It's a website where you can quickly generate lead sheets and draw chord charts using plain text. Even better, it can…

This started out when I vibe-coded a guitar scale fingering generator. It came out pretty good, and I started adding stuff to it: chords, then how chords and scales interact. Then I added charts for other instruments I mess around with: piano, cello, alto recorder. There's a complexity toggle to go from basic harmony to extended/experimental stuff. It's honestly still mostly a toy, but I thought other people might be interested in playing with it. Source is on github, so it's easy enough to run locally and fork. https://github.com/aleshh/gtr-scales

I built this app because I realized that I forgot about a song for a while and therefore got a lot worse at that song. The app will make you play your lowest-proficiency songs (something you just started learning) daily. Medium-proficiency songs (you can play them, but you have room for improvement) get played several times a week. High-proficiency songs (you have mastered them) are cycled through at the rate of approximately one-two per day. This app is in no way complete and probably contains bugs. With that being said, I have been daily-driving it in its current state for several days…
