How this service works
Separates mixed audio tracks into isolated vocals, bass, drums, and harmonic instrumental stems using DSP filter banks.
Output
Returns isolated audio stems for vocals, bass, drums, and harmonic instrumentals extracted from the input mixed audio file, each as separate audio data or URLs.
Example use cases
Karaoke track creation from song
“I want to make a karaoke version of this track — can you isolate just the vocals so I can remove them and get the instrumental backing? The file is at https://example.com/pop-track.mp3”
Remix production stem extraction
“I'm remixing this track and need the drums and bass separated out from everything else — can you split https://example.com/original-mix.mp3 into individual stems?”
Music practice backing track isolation
“Can you pull out just the bass line from this jazz recording at https://example.com/jazz-session.mp3 so I can practice along with it?”
Technical details
Endpoint
POSThttps://dt0ur.online/api/audio/stems?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to decompose a mixed audio recording into its component instrument layers — vocals, bass, drums, and harmonic instrumentals — for remixing, karaoke creation, music education, or audio analysis. Prefer this over generic audio processing tools when stem-level separation by instrument category is specifically needed.
Side effects
- Audio URL is not publicly accessible or returns 404
- Audio format not supported
- File too large or too long for processing
- Network timeout fetching remote audio
- DSP processing failure on corrupted or malformed audio
