Stem splitting and audio conversion running in-browser with Rust/WASM
What it is
What it does
It does stem separation (vocals/drums/bass/other), format conversion, BPM detection and speed/pitch changes.
Problem
Solves the issue of ugly 'free' audio conversion tools littered with ads.
Competition
The niche may be moderately saturated, as there's a mention of better server-side models (ElevenMusic), indicating competitive options exist.
Weaknesses
Stem separation quality is behind the best server-side models, Memory pressure on long files and Safari's WebGPU support are still rough edges
What could be built instead
Opportunity
To improve stem separation quality to match or exceed server-side models.
Vertical niche
Yes, it could be a vertical SaaS in audio processing for musicians and audio professionals.
MVP
A basic tool that performs audio stem separation and format conversion in the browser.
Differentiation
Runs entirely on your machine in the browser without uploading anything.
AI opportunity
AI can enhance the stem separation quality and speed of processing.
