Best Noise Suppression Software in 2026: 8 Tools Compared

Krisp is the best overall pick for remote workers because it works as a virtual audio layer across almost any call app. It removes background noise from your microphone and, on paid plans, from the other side of the call too, so a barking dog or a coffee shop hum stays out of the meeting. Processing for noise cancellation runs on device, which helps privacy, while newer meeting assistant features add notes and summaries for teams that want them.

The pricing change matters. Older free tiers offered daily minutes, but current pricing shows a seven-day trial and paid plans from $8 per user per month billed annually, with no permanent free tier on the live pricing page. Meeting assistant features also store recordings and transcripts in Krisp Cloud, so check retention controls before enabling them. For cross-app live cleanup, Krisp remains our top paid pick.

NVIDIA Broadcast is the free pick for anyone who already owns a compatible RTX graphics card on Windows. Its AI noise removal and echo removal clean up a microphone in real time, and the same app adds background blur, eye contact, and other video effects for streamers and callers. Since the tool is free and runs on hardware you already own, it costs nothing extra to try.

The limits are hardware and platform. You need an RTX GPU, and the app runs on Windows only, so Mac users and older PCs must look elsewhere. Performance cost also varies by GPU, so test with your own games or calls running. If you own an RTX card, start here before paying for any other live tool.

Adobe Podcast, including its Enhance Speech feature, suits creators who need to rescue a recording made in a noisy room. Upload audio, let the AI reduce noise and echo, and download a cleaner voice track that sounds closer to a studio recording. The web-based flow needs no install, and the free tier covers limited use, which suits occasional podcasters.

Adobe Podcast does not clean live calls, so remote workers should pick Krisp or NVIDIA Broadcast instead. Heavy users also need a paid Creative Cloud plan for larger limits. For a podcaster with one bad recording to save, Adobe Podcast is the easiest rescue tool on this list.

Audacity is the free, open-source editor that many creators use for manual noise reduction on recordings. Select a section of pure noise, build a noise profile, then apply reduction to the full track, with control over sensitivity and frequency smoothing. That manual control suits creators who want to tune the result rather than trust a fully automatic filter.

The process takes time and practice, and Audacity does not offer live AI suppression for calls. For a recorded podcast, interview, or voiceover, though, it delivers solid cleanup at no cost and runs on Windows, Mac, and Linux. Pair it with a good microphone technique and it covers most recording needs.

iZotope RX is the pro tool for audio repair, from removing hum and clicks to rescuing dialogue buried under noise. The Elements edition starts near $99, while higher editions add spectral repair, dialogue isolation, and batch tools that post-production teams rely on. For a film, broadcast, or podcast team that must save a critical recording, RX offers control that simpler tools cannot match.

The learning curve is real, and the full editions cost far more than Elements, so casual creators should start with Adobe Podcast or Audacity. Audio pros, though, will find RX worth the investment for its precision and repair depth. Test the trial on your hardest recording before buying a higher tier.

Waves Clarity Vx suits producers who clean dialogue inside a digital audio workstation, such as Pro Tools, Logic, or Cubase. The plug-in separates voice from background noise in real time, with controls for neural network processing that help on location recordings, interviews, and broadcast dialogue. That DAW fit matters, since it keeps cleanup inside the editing session rather than forcing a separate app.

Clarity Vx needs host software and a compatible system, and pricing varies by sale and bundle, so check the current Waves price before budgeting. Casual creators will find it more complex than Adobe Podcast. Producers who already work in a DAW will find it a fast, high-quality dialogue tool.

SoliCall Pro is built for call centres and enterprises that need noise filtering on every call, not just one worker's laptop. It combines echo cancellation with reference-based noise reduction, so agents in noisy rooms sound clear to customers and customers sound clear to agents. That two-way, enterprise-wide approach suits contact centres where call quality affects satisfaction scores.

Licensing is quote-based, and the tool is overkill for a solo remote worker who can use Krisp or NVIDIA Broadcast. IT teams should also check deployment and support terms for their phone system. For a call centre that needs consistent audio quality across many seats, SoliCall Pro is a proven enterprise pick.

NoiseGator is a free noise gate, which works differently from AI tools such as Krisp. Instead of identifying noise, it opens the microphone only when sound passes a volume threshold, so keyboard clicks and fan hum below that level stay silent. Gamers and streamers like it because it is free, light, and easy to route through virtual audio tools.

A gate is not AI suppression. It will not remove loud background noise that passes the threshold, and it needs tuning so quiet speech still opens the gate. The interface is also older than modern rivals. For a streamer on a budget who mainly needs to cut low-level noise between sentences, NoiseGator remains a useful free tool.
