Kill Background Hum & Hiss in Any Recording — in One Click
You hit record, you nail the take — and then you hear it. That steady electrical hummmm from a cheap cable. The constant shhhh of a noisy room. It’s the difference between sounding professional and sounding amateur, and re-recording usually isn’t an option.
Remove Background Noise with AI Magic ✨
Noise Removal fixes it for you. Drop in any audio or video file, let it auto-detect and tune out the noise, listen to a one-minute preview, and save a clean copy — your original is never touched.
Why You’ll Love It
- Kill the hum automatically — one click detects whether your recording has US (60 Hz) or European (50 Hz) electrical hum and tunes the filters to remove it.
- Preview before you commit — hear a one-minute sample with the cleanup applied so you never waste time on the wrong settings.
- Compare side by side — the A/B player flips between original and cleaned at the exact same moment, so you hear precisely what changed.
- Works on video too — clean the audio inside an MP4 and the tool rebuilds the video with the polished soundtrack, picture untouched.
- Match loudness standards — optionally bring your file up to YouTube, podcast, or broadcast loudness in the same pass.
- Your originals are safe — cleaned files are always saved as a new copy. The source is never overwritten.

Built for Real-World Recordings
Hear Exactly What Changed
The A/B Compare player keeps the playhead in the same spot when you switch sides — flip from the original to the cleaned version and you hear the identical moment, cleaned, with no jump. It’s the fastest way to confirm the voice still sounds natural.
Publish-Ready Loudness
Tick a box and Noise Removal brings your file to the right loudness for where it’s going — -14 LUFS for YouTube, -16 for stereo podcasts, -19 for mono podcasts, or -23 for broadcast — all in the same pass.
Three Proven Techniques, Combined
Under the hood, the FFmpeg engine stacks a harmonic notch (surgically removes the hum’s pitch and its echoes), a phase-cancel comb filter (kills the entire harmonic series at once), and an FFT denoiser (sweeps away broadband hiss) — and Auto-tune sets the strength for you, so you never have to think in decibels.
Stop Living With Noisy Audio
Whether you’re cleaning up an interview, a podcast, a course recording, or a family video, Noise Removal gets you a clean, professional result in minutes — without re-recording and without an audio-engineering degree.
