Pull the voice out of a noisy recording with the ElevenLabs voice isolator. Traffic, room echo, air conditioning, crowd, hiss and any music behind the speaker all come off and the speech stays, so a phone recording or a noisy location take can be used as clean dialogue. Pass the recording as source: an id from your library or a public https link. Nothing is added back, so the answer has no room and no music at all. Billed per 10 seconds of audio (a token quote applies) and the clean file is saved to your library. Returns audio_url, duration_seconds and generation_id.
