7 Best AI Noise Removal Tools in 2026

Key takeaways

• Adobe Podcast's Enhance Speech is the best AI noise removal tool for most people. It's free in the browser and rescues badly recorded speech in one click.

• iZotope RX 12 is the pick for professional control, and it keeps a voice sounding more like the original speaker.

• Accentize dxRevive drew the most votes in a Production Expert reader blind test of dialogue restoration plugins, and it can repair phone and codec audio, not just noise.

• For live calls, Krisp cleans up noise and background voices in every meeting app, and NVIDIA Broadcast does it free on Windows PCs with an RTX graphics card.

• Heavy noise removal can make a voice sound processed, so it's best to use the lightest setting that does the job.

What AI noise removal can fix

Older noise reduction tools learned a sample of steady noise, like hiss or an air conditioner, and subtracted it, which left watery artifacts when the noise changed. AI tools are trained to recognize a voice and keep only that, so they can also remove traffic, keyboard clicks, a barking dog, room echo, and even background music. Some work after recording, on a file, and others work in real time, as a virtual microphone for calls and streams. The tradeoff is that the strongest models rebuild the voice rather than just cleaning it, so the result can sound slightly different from the speaker. They can't fully save a clipped or distorted recording, though, and a decent microphone close to your mouth still beats any fix later.

How we ranked

We looked at how cleanly each tool removes noise and echo, how natural the voice sounds afterward, independent listening tests, real-time vs. file processing, control over the strength of the effect, file limits, platform support, and price.

The seven tools compared

1. Adobe Podcast Enhance Speech - Best for free one-click speech rescue

Enhance Speech is Adobe's browser-based tool that makes voice recordings sound like they were made in a studio.

What works: Upload a file and it strips out background noise and room echo in one pass, with no settings to learn. In ProVideo Coalition's May 2026 comparison against iZotope RX 12, it did best on the hardest clips, a phone recording with reverb and speech over heavy traffic. The free version handles audio files up to 30 minutes long, for up to an hour a day. Adobe's Firefly Pro plan, at $19.99 a month, adds a strength slider, video files, bulk uploads, files up to two hours long, and a music slider that can keep or remove background music.

What doesn't: It's built for speech only, it can change the character of a voice on heavy settings, and the free version has no strength control.

Best for: Podcasters and video creators who need to save a bad recording quickly and for free.

2. iZotope RX 12 - Best for professional audio repair

RX is the long-running audio repair suite used in film, TV, and music post-production, and version 12 arrived in April 2026. iZotope is now owned by Boris FX.

What works: RX handles nearly every kind of damage, with separate modules for noise, hum, clicks, clipping, and reverb, and Repair Assistant suggests a chain for you. Dialogue Isolate, rebuilt with new neural networks in RX 12, pulls a voice out of noise in real time or after recording. ProVideo Coalition found RX 12 handled steady noise best and stayed truer to the original voice than Adobe's web tool. Standard and Advanced run as a standalone app and as plugins inside your editing software. Elements costs $99, Standard $399, and Advanced $1,399, and Elements is also included in the $15-a-month iZotope Plus subscription.

What doesn't: The high-quality offline mode of Dialogue Isolate and Scene Rebalance, which splits dialogue, music, and effects, are only in Advanced, and RX takes time to learn.

Best for: Editors and audio engineers who want precise control over every fix.

3. Accentize dxRevive - Best for restoring badly damaged dialogue

dxRevive is a plugin that restores dialogue by rebuilding the voice, not just removing noise around it.

What works: In Production Expert's reader blind vote on dialogue restoration plugins, dxRevive Pro drew the most votes overall, ahead of Hush Pro, iZotope RX Dialogue Isolate, and others. Beyond noise and echo, it repairs codec artifacts and the thin sound of phone or band-limited recordings, which makes it useful for interviews recorded over a call. The Pro version adds more restoration algorithms, multiband control, and presets such as Restore Phone. It runs as a VST3, AU, or AAX plugin in most editing and audio software. dxRevive costs €99 and dxRevive Pro €299, both one-time, with a seven-day trial.

What doesn't: That vote ran in late 2023, before RX 12, and in Production Expert's 2025 shootout Hush Pro won more tests, though dxRevive Pro was called a solid all-rounder. Because it rebuilds the voice, it can occasionally make a speaker sound slightly different.

Best for: Editors rescuing interviews recorded over the phone or with poor microphones.

4. Krisp - Best for noise-free calls

Krisp is an app that cleans up your microphone and speakers in real time during calls.

What works: Krisp sits between your microphone and any meeting app, including Zoom, Teams, and Google Meet, and removes background noise, other people's voices, and echo. It also cleans the audio coming from the other side of the call. Noise cancellation is unlimited on every plan, and it runs on Mac and Windows. Core costs $8 per user a month billed yearly, or $16 monthly, after a seven-day free trial, and Krisp is SOC 2 Type II and GDPR compliant.

What doesn't: It's built for live calls, not for cleaning up recordings you've already made, and there's no permanent free plan on Krisp's own pricing page.

Best for: Remote workers and anyone who takes calls in noisy places.

5. NVIDIA Broadcast - Best for free real-time cleanup on Windows

NVIDIA Broadcast is a free Windows app that uses the AI cores on NVIDIA's RTX graphics cards to clean up audio and video.

What works: Its Noise Removal and Room Echo Removal effects work as a virtual microphone in streaming software, games, and call apps, and Studio Voice makes a basic microphone sound fuller. Version 2.3.0 added a File Processor mode for cleaning up saved MP4, M4A, MP3, and WAV files too. It's free, with no usage limits.

What doesn't: You need an NVIDIA RTX 2060 or newer graphics card on Windows, Studio Voice needs a more powerful card, and running it while gaming uses some of your GPU.

Best for: Streamers and gamers with an RTX graphics card.

6. Descript Studio Sound - Best for creators who edit in Descript

Studio Sound is the one-click voice cleanup tool inside Descript, a video and podcast editor that works through a transcript.

What works: Studio Sound removes background noise and room echo and regenerates the voice to sound like it was recorded in a treated studio, and you can apply it to a single layer or a track, with an intensity slider to control how strong it is. Because it's part of the editor, you can clean audio, cut mistakes, and export without changing apps. The free plan includes limited Studio Sound use, and Hobbyist costs $16 a month billed yearly or $24 monthly, with Studio Sound running on AI credits.

What doesn't: It's only available inside Descript, and on loud settings the voice can sound processed.

Best for: Podcasters and YouTubers who already edit in Descript.

7. Auphonic - Best for automated podcast post-production

Auphonic is a web service that runs a full audio post-production chain on podcasts and recordings.

What works: Its noise and reverb reduction can target steady or fast-changing noise and keep or remove music, and it can also remove breaths and mouth noises. A Studio Voice model rebuilds voices and repairs codec and clipping damage. Auphonic also levels volume between speakers and sets loudness for podcast platforms, so one pass gets a recording close to release-ready, and it has an API for automating the work. The free plan includes two hours of audio a month, and yearly billing saves 20% on paid plans.

What doesn't: Free productions get an Auphonic jingle added, and it offers less hands-on control than RX or dxRevive.

Best for: Podcasters who want cleanup, leveling, and loudness handled automatically.

Other options worth knowing

DaVinci Resolve Studio includes a real-time Voice Isolation tool, so editors who already own the $295 license get strong noise removal at no extra cost. Waves Clarity Vx is an affordable real-time noise removal plugin for music and video software. Cleanvoice removes noise along with filler words and mouth sounds in one pass. For free, open-source options, DeepFilterNet and RNNoise can run as real-time noise suppressors, and Macs from 2018 on have a built-in Voice Isolation mic mode for calls.
