Best Free Tools To Remove Noise From Audio

Audio noise gets in the way of high-quality podcasts, videos, and music. Background hum, keyboard clicks, wind noise, and room echo all distract from your message and undercut the professionalism of a recording. The good news: several free tools can clean it up. Here are the best, including how Rav.ai fits in.

Why clean audio matters

Background noise pulls your listener's attention away from your content. Whether you're a podcaster, YouTuber, or musician, audio quality can make or break you — distraction-free audio keeps people listening, and a clean listening experience builds a loyal audience.

Rav.ai

Rav.ai offers AI-driven noise reduction that automatically detects and removes unwanted noise, hum, hiss, and background chatter. It cleans your audio and improves clarity and dynamic range for professional-quality sound without manual editing. It needs no technical expertise and bundles other audio enhancements alongside noise reduction — ideal if you want clean audio with minimal effort.

Audacity

Audacity is a well-known, widely used free audio editor with a solid noise-reduction feature. You set up a "noise profile" from a quiet section, then apply noise removal across the file. It offers highly customizable settings and multi-track editing, making it a favorite of podcasters, musicians, and engineers — though it takes some time to learn.

Krisp

Krisp is a real-time, AI-driven noise-canceling app for calls and video conferencing that also works well for cleaning recorded audio. It filters out background noise like dog barking, keyboard typing, and fan noise. Install it, then select Krisp as your input or output device in your audio software.

Which should you use?

For hands-off, automatic cleanup choose an AI tool like Rav.ai or Krisp. For granular manual control, Audacity is hard to beat. Many creators use a combination depending on the recording.
