24 alternatives to Voice Composer – Browser-based pitch detection to MIDI/strudel/tidal
Built this over the weekend to bridge the gap between "can hum a melody" and "can code algorithmic music patterns" (Strudel/TidalCycles) for live coding and live dj'ing. What it does: Real-time pitch detection in browser using multiple algorithms: CREPE (deep learning model via TensorFlow.js) YIN (autocorrelation-based fundamental frequency estimation) FFT with harmonic product spectrum AMDF (average magnitude difference function) Outputs: visual piano roll, MIDI files, Strudel/TidalCycles code All client-side, nothing leaves your machine Why multiple algorithms: Different pitch…
Voice Composer is a browser-based tool that converts hummed or sung melodies into music notation and code. It uses real-time pitch detection through multiple algorithms—CREPE, YIN, FFT, and AMDF—to capture monophonic… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

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.

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.

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'm Gabe, the creator of Songcraft (https://songcraft.io/home). I recently dove headfirst into songwriting, and I quickly grew frustrated with my process. I found songwriting difficult enough without having to wrangle a mess of different tools, and there's no great solution to build chord sheets and tabs (unless you love pure text input). So, I built Songcraft - an online songwriting platform and tab builder. The drag-and-drop editor makes it easy to jump from chords to lyrics to melodies. I added a chord progression generator and chord recommendation engine to ensure…

Last April I shared about my Resonate project here (https://news.ycombinator.com/item?id=43694157) A lot has happened since: the work I presented in much more detail at last June's International Computer Music Conference (ICMC) got best paper award. I also gave a talk at the Audio Developer Conference in Bristol last November, the video is on YouTube). This year's work, which I recently presented at this year's ICMC, starts with known techniques from the phase vocoder literature to build self-tuning filter banks that extract very efficiently the frequency components that are…
