Every screen
Built for the one-handed moment.
The full noise-removal flow lives in six screens — no menus to hunt through, no settings to learn before you start.
Remove background noise from any recording with an on-device neural network. No uploads, no accounts.
Free · Works offline · iOS & Android
Tap unmute to hear the difference.
Built on a purpose-trained speech-denoising network that runs entirely on your device — no cloud round-trips, no servers in the loop.
Everything runs on-device, so there's no waiting for files to upload or for a server queue. Hit Clean and processing starts immediately.
Every byte of audio stays on your device. Use it on confidential calls, interviews, or unreleased music.
WAV, MP3, M4A (AAC), FLAC, MP4, MOV — and OGG, Opus, 3GP on Android. Video files are accepted too; we pull the audio out and write it back as audio.
No signal? No problem. The full denoiser is bundled in the app — works on a plane, in a basement, anywhere.
Send the cleaned file straight to Messages, Mail, AirDrop, Drive, or any app via the native share sheet.
The denoiser is language-agnostic — it treats speech in any language the same, cleaning noise without touching the words.
No editing skills needed.
Tap the picker and choose any audio or video from your phone. We support all major formats.
The on-device network strips background noise from the speech track. On a modern phone, processing is typically faster than realtime.
Toggle between the original and cleaned audio to hear the difference, adjust playback speed, then send the result through the system share sheet — Messages, Mail, Drive, anywhere.
The full noise-removal flow lives in six screens — no menus to hunt through, no settings to learn before you start.
One tap install. The whole noise-removal engine — model and all — ships in the binary, so the app works on a plane and never asks for an account.
No. Every step runs locally on your phone using an on-device neural network. Your files never leave your device. See our Privacy Policy for details.
Yes. The AI model is bundled with the app, so denoising works offline. You only need internet for the initial app download.
WAV, MP3, M4A (AAC), FLAC, plus MP4, MOV, and M4V for video — and additionally OGG, Opus, 3GP, and 3GPP on Android. Output is M4A (AAC) at 48 kHz.
Yes. The detail screen has an Original / Cleaned toggle, so you can A/B the same moment in the clip — switch sources without losing your place — and confirm the cleanup before you save or share.
It depends on the length of the clip and your device, but everything runs on-device with no upload wait. You can keep the app in the foreground and watch the progress bar.
Yes — NoisyNo extracts the audio track, cleans it, and lets you save or share the result. (Video re-muxing support is coming soon.)
The denoiser is language-agnostic — it works on speech in any language.
