A · DENOISE
Clear voice, every time.
Your voice stays warm and natural. Background noise — fans, traffic, AC, keyboard clatter — disappears. Powered by DeepFilterNet, the same class of model used by professional broadcast tools.

Studio-quality voice on your phone
Rescue any recording in one tap.
Denoise uses an on-device neural network to strip wind, traffic, hiss, hum and crowd noise from voice memos, interviews and videos. Import, clean and hear the full result free — you only pay to export.

What it doesThree kinds of mess.
Three kinds of mess.
One tap to fix it.
Denoise targets the patterns of human speech and pulls everything else away — without the watery, robotic artifacts older noise reducers leave behind.
B · WIND & CROWDS
Wind, crowds, and the world outside.
Recorded a video on a windy beach? An interview in a busy café? The model was trained on thousands of hours of exactly those environments, so it knows what to remove and what to keep.

C · RESTORE · PRO
Restore what's already lost.
For recordings that are clipped, muffled or recorded too far from the mic, the Pro engine rebuilds detail — even adding back high frequencies that weren't captured. The "I can't re-record this" rescue tool.

Demo voices: public-domain LibriVox audiobook recordings, mixed with real CC0 background noise (freesound.org, via DeepFilterNet assets). The “after” in every card is the real, unedited output of our on-device DeepFilterNet engine — no extra editing.
How it worksThree taps. No editor.
Three taps. No editor.
No timeline.
The whole point is that you don't have to learn anything. The model does the work; you tap a button.
STEP 01
Import
From Voice Memos, Photos, Files, or any app's share sheet. Voice memos, lectures, voice notes, video soundtracks — all welcome.
STEP 02
Denoise
One tap. The model runs on your device — even in airplane mode. Typically 5–10 seconds for a one-minute clip.
STEP 03
Hear & export
Compare before and after, then save, share, or replace the audio in your video. Exporting is the only thing Pro unlocks.

AI · AutoRecommended
Picks the right model for your recording. The one-tap default.
AI · DFN3Fast
Fast on-device denoise for everyday voice memos and clips.
AI · aTENNuateNew
Cleaner highs at the same speed — crisp dialogue and detail.
AI · VoiceFixerPremium · Restore
Rebuilds badly damaged, clipped or muffled audio.
Plus a Denoise + Restore chain and a Classical manual mode for full manual control.
Fine-tune with EQ
A 5-band EQ with Voice, Phone Call, Lecture and Music presets — plus “suggest a profile from the quiet part” so the noisier bands get cut more. Optional, for when you want it.
−16 LUFS
Broadcast-standard loudness
Automatic LUFS loudness normalization (−16 default, or −14 / −19 / −23) so every export lands at a consistent, platform-ready level. No guessing at gain.
See the noise, hear it gone
Toggle Original against Cleaned instantly and watch the strength slider work — so you trust the result before you ever export it.
New in v4.0Split the voice
Split the voice

Denoise now separates a track into vocals and instrumental — right on your phone. Pull a clean vocal out of a song or video, or drop the vocal for an instrumental and karaoke version. No stems to wrangle, no studio, nothing uploaded.
Isolate the vocal
Lift a clean acapella from any mix.
Keep the music
Make an instrumental or karaoke track.

★★★★★
“All gone! Within a minute.”
I record on my balcony and there is a lot of background traffic and wind noise. All gone! Within a minute of using the app!
★★★★★
“Beats my USB mic.”
I bought a USB microphone but this made little difference… As a last resort I downloaded Denoise on my phone and was pleased to find it improved sound quality by a HEAP, got rid of all the background noise and static… highly recommend if you are filming videos and want them to be professional.
★★★★★
“No robotic artifacts.”
Best one I could find on iOS and straightforward to use… all the other apps left the remaining audio sounding like robots.
★★★★★
“Close to cinematic sound.”
This is great for canceling noise in the background with the mic that I have. It catches a lot of hiss and this app cleans that up very nice for very close to cinematic sound.
★★★★★
“Incredible for the price.”
This app is incredible for the price, removed a lot of distracting noise from my audio including a TV in the background which is hard to do.
★★★★★
“Better than others.”
Better than others because you can adjust the level of noise removal.

M4A audio by default; MP3 or WAV optional; or a new video with the cleaned audio replacing the original. Saving and exporting is the one thing Pro unlocks — listening to the result is always free.
Yes — new in v4.0. The Music engine splits a song or video soundtrack into vocals and instrumental on-device: isolate the voice, or keep the music for a karaoke/instrumental track.
For voice cleanup, Denoise reduces background music while keeping the speech natural. If you want to fully remove or keep the music, use the dedicated Music engine to separate the two.
There's no length limit, free or Pro. Denoise anything from a 10-second voice note to a 3-hour lecture; you only pay when you export.
No. The model runs locally on your iPhone or iPad's Neural Engine. There is no server-side component to Denoise.
