AI Noise Reduction · 100% On-Device · Apple Silicon
AI Noise Reduction for Mac, Clean Voice in Seconds.
Aulio Studio removes hum, hiss, fans, air conditioning, traffic, wind and room noise from your recordings with a neural network that runs on your Mac.
No noise profile to capture. No uploads. No hollow, underwater voice.

What AI noise reduction removes
The model keeps anything that sounds like a human voice and turns everything else down. That covers steady noise and noise that changes from second to second.
Electrical hum, preamp hiss, cable buzz and ground noise.
Laptop fans, HVAC, fridges and computer whine.
Street noise, passing cars, wind on the mic in outdoor recordings.
Cafes, events and open offices behind the speaker.
Keyboard clicks, dogs, birds and horns, even when they overlap the voice.
Turn on de-reverb in the same pass to dry out echoey rooms.
How to use AI noise reduction on a Mac
Drop in your file
MP3, WAV, FLAC, M4A, or a video (MP4, MOV). Batch several files at once if you have a whole season.
Preview A/B
Play any section and switch between original and cleaned, loudness-matched, before anything is processed.
Set the strength
One slider controls how much noise is removed. Add de-reverb or filler word removal in the same run.
Export
WAV, MP3, M4A, FLAC or AIFF, or the full video with the cleaned audio track in place.
AI noise reduction vs traditional noise reduction
Classic noise reduction, like the effect in Audacity or a noise gate in Logic, asks you to select a few seconds of "silence" so it can learn a noise profile. It then subtracts that profile from the whole file. That works for steady hiss, but it fails when the noise changes, and pushing it harder leaves the voice thin and watery.
AI noise reduction works the other way round. The neural network was trained on large amounts of clean speech and on many kinds of noise. For every few milliseconds of audio it predicts which frequencies belong to the voice and which belong to noise, then keeps the voice. Because it learns what speech sounds like rather than what one noise sounds like, it handles traffic, chatter and clicks that a profile can't capture. A noise gate can't tell a quiet voice from hum at the same level; the AI model can.
| Traditional (noise profile / gate) | AI noise reduction | |
|---|---|---|
| Setup | Capture a noise sample, tune thresholds | None, works on drop |
| Changing noise | Poor: only removes the sampled noise | Good: traffic, chatter, clicks |
| Voice quality at high strength | Hollow, "underwater" artifacts | Voice stays natural |
| Quiet speech under hum | Gated out along with the hum | Kept |

Why on-device AI noise reduction is better on a Mac
Most AI noise reduction tools are websites: you upload the file, wait in a queue, and download the result. Aulio Studio runs the model on your Mac's Apple Silicon chip instead.
- Fast. A two-minute recording cleans in about 20 seconds on an M1 and about 8 seconds on M4. A 30-minute episode is done in under 3 minutes.
- Private. Interviews, client calls and legal audio never leave your Mac. See on-device AI audio privacy.
- No limits. No file size cap, no monthly minutes, no internet needed after install.
- Inside Logic Pro. The Aulio Clear AUv3 plugin runs the same AI noise reduction in real time in Logic Pro and GarageBand.

AI noise reduction FAQ
What is AI noise reduction?
AI noise reduction uses a neural network trained on clean speech and many kinds of noise. Instead of subtracting a fixed noise profile, it predicts frame by frame which parts of the sound are voice and which are noise, so it can remove changing noise like traffic, chatter and keyboard clicks without making the voice sound hollow.
What is the best AI noise reduction app for Mac?
For voice recordings, Aulio Studio is built for this job: AI noise reduction that runs 100% on your Mac, works on existing audio and video files, adds filler word removal and transcription, and costs $49 one-time. iZotope RX is the pro option for audio engineers at $399+, Krisp only filters live calls, and Adobe Podcast uploads your audio to the cloud.
Does AI noise reduction work offline on a Mac?
Yes. Aulio Studio runs the noise reduction model on your Mac's Apple Silicon chip. After installing the app, no internet connection is needed and your recordings are never uploaded.
How fast is AI noise reduction on Apple Silicon?
A two-minute recording cleans in roughly 20 seconds on an M1 Mac and closer to 8 seconds on M4. A 30-minute episode finishes in under 3 minutes on Apple Silicon. More in audio cleaning on Apple Silicon.
Can I use AI noise reduction inside Logic Pro?
Yes. Aulio Clear is a real-time AUv3 noise reduction plugin for Logic Pro, GarageBand and other AUv3 hosts. It is included with Aulio Studio Pro and the monthly plan, or available as an add-on.
Can it remove noise from a video?
Yes. Drop an MP4 or MOV file in. Aulio Studio removes the noise from the audio track and exports the video with the cleaned audio, or the audio on its own.
Is there a free trial?
Yes. Aulio Studio has a free 10-day trial with every feature and no credit card. After that, choose $49 one-time, $99 one-time with the Logic Pro plugins, or $9.99 per month.
