Audio repair tools
Fix hum, clicks, harsh highs and more.
How the audio repair tools work
How it works
Each tool targets one problem. Choose the tool that matches what you hear, upload a mono or stereo file, set the amount, and compare the result with the original. Processing runs in your browser, and the original file is never changed.
What each tool does
- Remove hum: narrow notch filters at 50 or 60 Hz and the next three harmonics.
- Remove clicks: finds single-sample spikes and replaces them with the average of the samples on either side.
- De-esser: turns down the band above about 4.5 kHz only while it is loud, which reduces harsh S and T sounds.
- Phase repair: flips the polarity of the left or right channel and removes DC offset.
- Stereo repair: narrows the stereo width, up to a full mono fold-down.
- Clipping and harshness: redraws clipped peaks and lowers harsh high frequencies.
- Muddy mix: reduces low-mid build-up and opens up the top.
What you get
A WAV file of the repaired audio, ready for mastering or for another repair step. You can run several tools one after another, for example hum removal, then the de-esser, then mastering.
Good to know
- Hum notches also lower musical notes that sit on those exact frequencies.
- Click removal is built for short digital spikes, not long crackle or vinyl noise.
- On a full mix, the de-esser also affects cymbals and other bright sounds.
- Narrowing stereo width cannot recover sound that cancels when summed to mono.

Questions.
Can these tools remove reverb or background noise?
No. They reduce hum at fixed frequencies, isolated clicks, sibilance, polarity and DC problems, excess stereo width, clipping and harshness. Reverb, hiss and general background noise are not handled.
Which tool should I use for a harsh or clipped AI track?
Use the Suno audio fixer. It smooths flat-topped peaks and lowers harsh ranges around 2 to 4.5 kHz and 8 to 16 kHz. Use the de-esser instead when the problem is only loud S and T sounds in a vocal.
Is my audio uploaded?
No. The repair tools process the file in your browser, and it stays on your device.
Can I hear the result before I download it?
Yes. Each tool lets you compare the original and the repaired audio before you export. Downloads need a membership.
What can't it do?
These tools reduce specific problems. They do not remove reverb, rebuild heavily clipped audio, or restore detail that is missing from the recording.
