Does it work on Udio and other AI music?

Yes. The processing works on any audio file. It was tuned for problems common in Suno exports, but it does not depend on which generator made the track.

Which de-sheener setting should I use?

Start with Medium, the default. If cymbals or vocals lose too much brightness, switch to Subtle. Use Strong only on very harsh tracks, and compare with the original.

Will it make my track louder?

Only up to a peak of 0.95 of full scale. It does not add compression or limiting. Use AI mastering afterwards to set the final loudness.

Is my audio uploaded?

No. All processing happens in your browser.

How it works

The file is decoded in your browser and processed in three steps. Nothing is uploaded.

De-clipper: finds runs of samples stuck at or near full scale and redraws them as a smooth curve between the samples on either side. You can turn it off.
De-sheener: works in the frequency domain. It smooths and slightly lowers the 2 to 4.5 kHz range, where a harsh, metallic tone often sits, and smooths and lowers the 8 to 16 kHz range, where fizz and shimmer sit. Choose Subtle, Medium or Strong, or turn it off.
Normalize: sets the peak of the result to 0.95 of full scale, with all channels adjusted together so the stereo balance stays the same.

What you get

A 16-bit WAV of the repaired track at the original sample rate. The results panel lists how many clipped regions were repaired, which de-sheener setting was used and the peak level change. Play the original and the fixed version to compare before you download. Downloads need a membership.

Good to know

Redrawn peaks are an estimate. Heavily clipped audio cannot be fully restored.
The de-sheener lowers bright frequencies for every sound in those ranges, including cymbals and vocal air. Start with Subtle or Medium.
It cannot add detail that is missing from the file, and it does not guarantee removal of all AI artifacts.
Files up to 100 MB and 15 minutes.
