Voice Isolator

Voice Isolator helps you keep only the speech from a noisy recording. Drop in an audio or video file and remove background problems like hum, hiss, wind, traffic, fans, and room noise—without needing any software installed.

You get two engines for different situations. Noise cleanup runs directly in your browser using the DeepFilterNet3 neural network, so it’s free and unlimited and your file never leaves your device. It outputs a cleaned voice track you can listen to immediately and download.

When there’s background music under the voice, switch to AI voice isolation. This mode removes background music (and other sounds) by isolating the voice using a cloud GPU model. It accepts longer recordings (up to 10 minutes) and returns separated voice and background tracks.

Voice Isolator works well for podcasters, interviewers, video creators, students and researchers, journalists and legal teams, and anyone trying to salvage a precious recording. Noise cleanup can be especially helpful when you need privacy, since processing stays in the browser. Plans/pricing: noise cleanup is free and unlimited, while AI voice isolation costs 1 credit per minute.

What does Voice Isolator remove from my recording?

Noise cleanup targets hum, hiss, wind, traffic, fans, and other room noise while keeping the voice natural. If music is playing behind the speaker, AI voice isolation can strip the background music as well.

Does noise cleanup upload my file?

No. Noise cleanup runs in your browser, so your recording isn’t uploaded for processing.

How is AI voice isolation different from noise cleanup?

Noise cleanup removes non-speech noise on your device. AI voice isolation separates the voice from background music (and other sounds) using a cloud GPU process.

What file types and how long can I process?

You can use MP3, WAV, M4A, FLAC, and MP4/MOV video (and other supported formats listed in the app). Files up to 10 minutes and 100 MB are accepted.

What do I get back after processing?

Noise cleanup returns a cleaned voice track (downloadable as WAV or MP3). AI voice isolation returns separated voice and background tracks (MP3/WAV).

How much does it cost?

Noise cleanup is free and unlimited. AI voice isolation is priced at 1 credit per minute.
