How it works

Import Your Track

Paste a Suno link or upload the file.

Restore the Audio

Reduce metallic artifacts, harsh highs, and encoding damage thanks to specialized AI models that regenerate high frequencies

Master the Result

Use reference-based mastering for a cleaner tonal balance.

Fix the Source Before You Master It

If the track already has hiss, metallic tone, or smeared highs, normal mastering usually makes it worse. Regenerate high frequencies with restoration first so you are working with a cleaner source.

What People Mean by "Suno Hiss"

It is usually not just hiss. What you hear is often a mix of metallic tone, smeared highs, weak transients, and a boxed-in midrange.

Metallic or hollow vocals
Grainy highs and smeared reverb tails
Boxed-in mids
Weak drum transients
Busy sections that collapse together

What You Can Do About It

Restore the damaged parts first, then master the cleaner file. That gives you a better chance of getting smoother highs, more natural vocals, and a mix that opens up instead of getting harsher.
