What is ElevenLabs Audio Isolation?
ElevenLabs Audio Isolation extracts the vocal stem from any mixed audio file. The call shape is intentionally minimal: send one required field, audio_url, and the endpoint returns a single output URL with the vocal track lifted clear of music, ambient noise, and instrumental layers. There are no other parameters to set; the model handles separation internally. Output is the dry vocal, ready for tuning, double tracking, vocal-only remix prep, captioning, or downstream voice processing. The endpoint is scoped to vocal isolation specifically; for multi-stem separation from a Suno track, the Suno stems route splits drums, bass, vocals, and other parts using a clip_id.
Key features of ElevenLabs Audio Isolation
Three features cover the entire surface area.
Single-call vocal isolation
One required field, `audio_url`. The endpoint returns the isolated vocal stem with no other parameters to tune. The simplicity is the point: drop a URL in, get a vocal track out.
Source-agnostic input
Mixed music, podcasts, field recordings, voice memos with background music, dialogue with ambient noise. The model takes any audio URL and pulls the vocal layer out without per-source configuration.
Clean dry vocal output
The result is a vocal stem that drops directly into a DAW for tuning, doubling, or remix. No second cleanup pass required for typical music or podcast sources.
Best for
Remix and edit prep
Float a dry vocal for tuning, double tracking, or sample-style remix work. Drop the result straight into a DAW timeline.
Creative sampling from licensed sources
Lift vocal moments from material you have rights to use. Useful for production work that wants the vocal phrasing without the original instrumentation.
Archive cleaning
Pull speech out of music-heavy archive recordings for review, accessibility, or transcription. Useful when an interview was recorded over a venue PA or a noisy room.
Mashup sketches
Pair an isolated vocal line with a new beat or bed. Useful for prototyping before committing to a final mix.
Dubbing and translation prep
Reduce competing music underneath dialogue so a translator or voice artist can hear the source clearly before re-recording.
QA listens before release
Verify lyric clarity by listening to the vocal alone. Catches phrasing or pronunciation issues that the full mix can hide.
Use cases
Drop a song into the endpoint to pull a clean vocal for tuning before a remix project, then take the result back into the DAW for double tracking. Run an archive of interview recordings made over noisy venue PAs through the endpoint and feed the cleaned vocal stems into a transcription pipeline. Stage a mashup sketch by isolating the lead vocal from one track and laying it over a fresh instrumental bed for a rough cut. Send a finished mix through the endpoint for a QA listen, where the isolated vocal makes phrasing and pronunciation issues easier to catch before release.

FAQs

Audio Isolation extracts the vocal stem from a mixed audio file. Upload a song, podcast, or recording via audio_url, and the endpoint returns a single audio URL with vocals lifted clear of the music and noise underneath.
One required field, audio_url. There are no other parameters: the model takes the source URL and returns the isolated vocal track. The simplicity is the point; everything else is handled internally.
A single audio_url with the dry vocal stem. The output is suitable for tuning, doubling, vocal-only remixing, captioning, or downstream voice processing.
Audio Isolation returns vocals only. Tools like Demucs split a mix into multiple stems (drums, bass, vocals, other) but require local setup. This endpoint focuses on getting one clean vocal stem out of any source via a single hosted call.
Not from this endpoint. It returns the vocal stem only. For multi-stem separation from a Suno track, use the Suno stems route. For arbitrary multi-stem splits, run Demucs locally.
Mixed music with audible vocals, podcast or recording with background music, dialog with ambient noise, and field recordings with mixed-in voice. Sources where the vocal is buried so deep it is barely audible may not separate cleanly.
No. Suno stems split a Suno-generated track into multiple parts using its clip_id. Audio Isolation works on any uploaded mix, regardless of where the audio came from, and returns vocals only.
