Quality note
- Fast and Better run entirely in this page and use stereo + frequency analysis. They are intended for practice, remix sketches, sampling, and quick isolation.
- HQ AI opens a browser Demucs implementation for true neural stem separation. It requires a much larger model than this lightweight GitHub Pages tool includes.
- For best local results, use a stereo mix with clear center vocals and avoid heavily mono-mastered audio when possible.
