Suno keeps flagging my upload?
Sometimes Suno refuses an audio file because it thinks the track is already in its database — even if you have the right to use it. We built Suno Audio Anonymization, a small tool that runs in your browser to help.
50 songs tested. All passed.
We ran Suno Audio Anonymization against 50 tracks that Suno had previously rejected as known works. Every single one passed the upload check after processing. Most cleared on Moderate; a handful of stubborn cases needed the Aggressive preset.
What it does
The Suno Audio Anonymization tab takes your audio and gently re-renders it. The result still sounds like your track to a human ear, but Suno's upload check sees it as new material.
Everything happens on your computer. The file never reaches our servers — there are no servers in the loop. Close the tab and the audio is gone.
How to use it
- Open the Suno Audio Anonymization tab.
- Drop in your audio file.
- Pick a preset — Subtle, Moderate, or Aggressive. Moderate is a good default.
- Click the button.
- Download the result and upload it to Suno.
If Subtle still gets flagged, try Moderate. If Moderate gets flagged, try Aggressive. Most uploads sail through on Moderate.

The tool lives next to Local OCR on the home page. No account, no upload, no quota.
