ElevenLabs Voice Isolation

Some nodes are kitchens with a dozen knobs. This one is a light switch. ElevenLabsAudioIsolation takes one audio input, strips the background noise, and hands back the clean vocals. No settings, no model dropdown, no seed. You can't even tune it. That's the whole interface.

It's a partner node, so the cleanup happens on ElevenLabs' servers through Comfy's API proxy rather than on your machine - you log in with your Comfy account (Settings → User) and it draws from your prepaid credits (Settings → Credits), billed per minute of processed audio. No ElevenLabs API key needed. If you ever want the entire partner-node family gone from your menu, start ComfyUI with --disable-api-nodes.

Why you'd actually reach for it

Rough recordings. A voice memo with a fan humming, a phone recording with traffic, a clip where the "room tone" is loud enough to wreck a mix. Wire any AUDIO source in - LoadAudio, another node's output, even something you just generated - and the cleaned result comes out the other side. It's the fastest route to a usable voiceover when you can't re-record.

It's also a useful pre-processing step inside a bigger chain. Pair it with ElevenLabsSpeechToText to transcribe a noisy recording accurately, or run your samples through it before voice cloning to keep the hum out of the clone.

The one input and the one output

• audio - whatever you want cleaned. That's it.
• Output: AUDIO, straight into Preview Audio, Save Audio (Advanced), or any downstream audio node.

Honest expectations

• You get speech isolation, not a general mastering suite. It's built to pull vocals forward and push noise down; don't expect it to also fix distortion or level the mix.
• It's a paid call per minute of audio. For a long recording that adds up, so trim before you clean, not after.
• Because there are no settings, there's no recovery if the source is too far gone - heavily music-layered or heavily compressed audio may come back thin. Keep the original and A/B it.

It ships with ComfyUI core (landed February 2026), so nothing to install. For a one-click noise remover that's genuinely one click, this is the node.
