ElevenLabs Audio Isolation
elevenlabs/audio-isolation extracts clear speech from an audio or video recording by removing background noise, music, room interference, and competing environmental sound. Unlike a general denoiser aimed at polishing every element, Audio Isolation prioritizes the spoken voice so dialogue remains intelligible even when the original capture was made in a difficult location. This combination makes the model a practical choice when the creative outcome depends on those qualities rather than on a generic media conversion.
For production work, It is useful before transcription, dubbing, editing, or publishing interviews and field recordings, where cleaner dialogue improves both human listening and downstream speech processing. The result is most reliable when the source material and creative brief clearly describe the intended subject, progression, visual or sonic character, and the qualities that must remain unchanged.
Highlights
Voice-first separation isolates spoken dialogue from complex background sound.
Noise and music removal cleans recordings captured in uncontrolled environments.
Speech intelligibility improves before transcription, editing, or localization.
Audio-from-video support recovers dialogue directly from recorded footage.

When to Use
| ✅ Good fit | ❌ Consider alternatives |
|---|---|
| The model's named workflow matches the source material and intended output | A different input modality or model route is required |
| A managed asynchronous result is suitable for the production pipeline | A synchronous, interactive editor is essential |
| The documented controls cover the required duration, framing, or format | The project needs controls outside this endpoint's schema |
| Creative iteration benefits from a repeatable request structure | Exact deterministic pixels, frames, geometry, or samples are mandatory |
| A finished downloadable media asset is the desired deliverable | Editable source layers or a native project file are required |
Prompt Guide
For audio transformation, state the intended result first, then add the subject or source treatment, progression, style, and delivery constraints. Keep one creative variable per phrase, use the documented field names for controls, and change one setting at a time when comparing results.
