A · DENOISE
Clear voice, every time.
Your voice stays warm and natural. Background noise — fans, traffic, AC, keyboard clatter — disappears. Powered by DPDFNet and DeepFilterNet 3, open speech-enhancement models that run on your phone.

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 models learned from thousands of hours of speech mixed with noise like this, so they know what to remove and what to keep.

C · RESTORE
Restore what's already lost.
For recordings that are clipped, muffled or recorded too far from the mic, AI · Sidon 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 readings mixed with real CC0 background noise (freesound.org, via the DeepFilterNet project), not field recordings. Each “after” is the unedited output of DeepFilterNet 3, the model behind AI · Fast Denoise, from its open-source release; the app's default, AI · Auto, runs DPDFNet, from the same family.
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
Remove the noise
One tap. The model runs on your device, even in airplane mode. A one-minute clip takes about 10 seconds on a recent phone.
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.
New: record in DenoiseRecord it clean.
Record it clean.
Nothing to fix later.
Tap + and choose Recorder. Denoise removes background noise while you record, so the cleaned recording is ready the moment you stop. Everything stays on your phone.
Cleaned as you record
Live on phones fast enough to keep up. On the rest, the clean-up starts the moment you stop.
Keeps going with the screen locked
Pause, resume or stop from the Lock Screen or the notification. A call pauses it; Resume continues the same take.
Nothing gets lost
Every second is saved as it is recorded. If the app closes, the recording is back in your library.

Plus a Restore speech quality switch for phone-quality recordings 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.
−14 LUFS
Broadcast-standard loudness
Automatic LUFS loudness normalization (−14 default, or −16 / −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.
AI · MusicSplit the voice
Split the voice
from the music.
Denoise 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.

AI · ShortenCut the pauses.
Cut the pauses.
Keep every word.
AI · Shorten trims the long pauses and speeds up the speech a little, without changing the voice. A 73-minute lecture comes out at about 50 minutes. Short pauses stay, so it still sounds like someone talking.
Shorter pauses
Long gaps shrink in proportion. Short ones stay, and you can keep any pause whole.
Faster speech, same voice
Up to 1.5× with the pitch unchanged, or keep the pace and cut only the pauses. One slider sets how much.

Five jobs Denoise was built for. If yours isn't here, it probably still works — try it free.
For podcasters
Cut hours of post-production. Run a whole episode on the train home.
For creators
Reels, TikToks and Shorts that sound like you used a $300 mic.
For journalists
Salvage interviews recorded in less-than-ideal rooms. Hand a clean track to your transcription tool.
For students
Lecture recordings you can actually study from — even from row 20.
For everyone
That holiday video. That toddler's first words. That voice memo you can barely hear.

★★★★★
“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.
FAQEverything people ask

Anything else? support@routes.tips — we read every email.
Yes. Noise removal runs on your phone, so it works on a plane, in a tunnel or anywhere else without service. The main models come with the app; a few optional ones, such as vocal separation and AI · Sidon, download once the first time you use them, then work offline too.
No. Importing, denoising and hearing the full before/after is free — no account, no trial countdown. You only pay when you want to save or share the cleaned file: 3 exports for $1.99, or Pro for $2.99/mo or $14.99 once ($11.99 on Google Play).
Almost any audio or video: M4A, MP3, WAV, AAC, MP4 and MOV, and WhatsApp or Telegram voice notes. Open them from Voice Memos, Photos or Files on iPhone, from the gallery or file manager on Android, or send them from any app's Share menu.
M4A audio by default, or WAV; 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. AI · Music splits a song or a video's soundtrack into vocals and instrumental on your phone: isolate the voice, or keep the music for a karaoke or instrumental track.
Yes. AI · Shorten trims the long pauses and speeds up the speech, up to 1.5×, without changing the pitch, or cuts only the pauses if you prefer. Short pauses and every word stay; a 73-minute lecture comes out at about 50 minutes.
Yes, on iPhone, iPad and Android. Tap + and choose Recorder: Denoise removes background noise while you record on phones fast enough to keep up, and right after you stop on the rest. Recording continues with the screen locked, and nothing is uploaded.
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 AI models run locally on your iPhone, iPad or Android phone, and your recordings never leave it. The app sends only usage and crash reports, never audio (see the privacy policy).
Yes — Denoise is on Android too. Grab it from Google Play, or get it on the App Store for iPhone and iPad. Same one-tap, on-device cleanup on both.
Purchases go through the App Store or Google Play, and so do refunds: on iPhone and iPad, ask Apple at reportaproblem.apple.com; on Android, ask Google Play, or write to us and we can refund a Google Play order ourselves.
