Diamond Stem Studio, in four stems
A browser-based audio workspace that separates mixed songs into vocals, drums, bass, and other, then builds instrumentals, a cappellas, and karaoke mixes.
- For
- Karaoke singers and musicians making practice or remix stems
- Worth noticing
- Cleanup is a separate finishing pass, so bleed can be reduced without rerunning the heavier separation step.
Field notes
The interface offers three separation paths: HTDemucs, spectral extraction, and center-cancel, with GPU status and an option to load an ONNX model from disk. Its manual describes cleanup as a separate pass that can be reapplied without repeating separation; exports include 16-bit, 44.1 kHz WAV files and a ZIP of the stems. Lyrics can be searched in LRCLIB, loaded as .lrc, or pasted and tap-synced; the karaoke view keeps lyrics on the user's screen.
