Best Audio Noise Reduction Software in 2026: 9 Tools Compared

#1

iZotope RX

Best for: Post teams needing the deepest repair toolkit

Visit izotope.com

RX is the tool audio post professionals reach for when a recording is genuinely damaged. The current RX 12 line spans three editions: Elements at $99 for quick repairs, Standard at $399 with the standalone editor and core spectral tools, and Advanced at $1,399 for full post-production work.

That depth comes with a learning curve and a bill. If your problem is steady background hiss on a podcast, RX Standard is more tool than you need. One more thing to know: iZotope has joined the Boris FX family, so RX now sits alongside CrumplePop and the company's video tools under one roof. For teams that regularly rescue location dialogue, audiobooks, or broadcast audio, nothing else in this list goes as deep.

#2

Adobe Audition

Best for: Video teams already on Creative Cloud

Visit adobe.com

Audition makes the most sense if your team already lives in Creative Cloud. The spectral frequency display lets you see noise and paint it out, and the Effects Rack plus diagnostics (DeNoise, DeReverb, DeClicker) handle routine cleanup inside a familiar multitrack editor. Round-tripping with Premiere Pro means video editors can send audio over, fix it, and get it back without exporting stems by hand.

The catch is the business model and the ceiling. At $33.99 per month for the single app (or bundled in an All Apps plan), you rent forever, and Adobe's built-in noise tools do not match the latest AI plugins for difficult speech. Audition is the right pick when noise reduction is one task inside a larger audio and video workflow, not when it is the whole job.

#3

Audacity

Best for: Zero-budget podcast and voiceover cleanup

Visit audacityteam.org

Audacity has been the default free audio editor for over two decades, with more than 100 million downloads, and its noise reduction effect still gets the job done on steady hiss and hum. You sample a few seconds of room tone, apply the effect, and adjust the reduction amount. It also handles click removal, normalization, and basic spectral selection for spotting problem frequencies.

It is not in the same league as the AI tools for difficult material, and the workflow feels old: mostly offline processing, limited real-time preview, and an interface that has barely changed. But the price is zero, forever, with no tiers or trials. For a small team producing a podcast or voiceovers on no budget, Audacity plus a decent microphone covers most cleanup needs.

#4

Waves Clarity Vx

Best for: Podcasters wanting one-knob voice cleanup

Visit waves.com

Clarity Vx is the plugin people buy when they are tired of tweaking noise profiles. Two built-in neural networks, trained on hundreds of thousands of vocal recordings, tell voice apart from ambience automatically. You turn one knob and the air conditioner, fan, and traffic fade while the voice stays intact. It runs in real time, works in mono and stereo, and loads as VST3, AU, or AAX in any major DAW.

Two honest caveats. It is CPU-hungry and introduces significant latency (2,048 samples at standard sample rates), so your DAW's delay compensation must be on. And Waves prices move constantly; the street price sits around $34.99 to $39.99 against a much higher list price, so buy during one of the endless sales. A Pro version exists for heavier post-production duty at a higher tier.

#5

Accentize DeRoom Pro

Best for: Dialogue recorded in echoey rooms

Visit accentize.com

DeRoom Pro does one thing exceptionally well: removing room reverb and echo from speech. Its neural network was trained on many different room scenarios, so it separates direct sound from reflections and even estimates the room size automatically. Reviewers consistently rate it above the de-reverb in general repair suites for natural-sounding results, and it processes in real time with a choice of waveform or spectrogram visualization.

It is a specialist, not a suite. On guitars, drums, or piano it is far less effective, because the model was trained on speech. The $259 one-time price reflects the pro positioning, and licensing runs through iLok. A free trial is available, and you should use it on your worst-sounding room recording before buying. For podcasters and video teams stuck with untreated rooms, it can make a home office sound close to a treated booth.

#6

Acon Digital Restoration Suite

Best for: Budget editors wanting a full repair bundle

Visit acondigital.com

Acon Digital's Restoration Suite 2 packs four restoration plugins into a $99.90 bundle: DeNoise 2 for hiss and broadband noise, DeHum 2 for electrical hum, DeClick 2 for clicks and crackle, and DeClip 2 for clipped audio. Version 2 added dynamic noise profiles that track noise changing over time, which is exactly what you need for wind or lavalier rustle, plus mid/side processing and surround support.

The tradeoff for the price is polish and ecosystem. Acon is a small Norwegian company, so you get fewer video tutorials and a smaller user community than iZotope or Waves buyers enjoy. Demo versions are available to try before buying. If you want a complete repair toolkit without spending several hundred dollars, this is the value pick of the category.

#7

CrumplePop

Best for: Video editors wanting dead-simple cleanup

Visit borisfx.com

CrumplePop, now part of Boris FX, is built for video editors who never wanted to learn audio repair. The bundle includes AudioDenoise, EchoRemover, WindRemover, TrafficRemover, and Levelmatic, all with minimal controls and real-time playback. Two plugins, PopRemover and RustleRemover, are free forever, which alone solves plosives and lavalier rustle for a lot of creators.

The full CrumplePop Complete bundle's price was not published on the vendor site at the time of writing, so check before budgeting. And simplicity cuts both ways: when a one-knob tool guesses wrong, there is less to adjust than in RX or Acon's suite. For YouTubers, course creators, and small video teams, though, the speed from problem to clean audio is the point.

#8

NVIDIA Broadcast

Best for: Streamers and remote workers with RTX GPUs

Visit nvidia.com

If you own a compatible NVIDIA GPU, Broadcast is the best free lunch in audio cleanup. It creates a virtual microphone that strips fan noise, keyboard clicks, and room echo in real time before the audio reaches Zoom, Discord, OBS, or any other app, and it can clean up incoming audio from noisy callers too. It uses only a small slice of GPU resources and takes minutes to set up.

The limits are hardware and platform. You need an RTX 2060 or newer on Windows 10 or later; there is no Mac version, and it is a live processor, not an editor for recorded files. For streamers, remote workers, and anyone on calls all day with an RTX card already in the machine, there is no reason not to install it.

#9

Krisp

Best for: Remote teams taking calls anywhere

Visit krisp.ai

Krisp sits between your microphone and every calling app, removing background noise from your voice and optionally from the other side too. Because it works at the audio-device level, it covers Zoom, Teams, Meet, Slack, and anything else without per-app setup.

Pricing starts at $8 per user per month billed annually, with a 7-day free trial of everything. Krisp has grown into a broader meeting platform with transcription, AI notes, and accent conversion, which is great if you want it and bloat if you do not. For distributed teams taking calls from homes, cafes, and co-working spaces, it is the most flexible cross-app option here.
