Not a high cut
It finds the artifacts, not the treble.
Low-passing at 12 kHz makes a bad recording duller, not better. This detects the synthetic patterns specifically, so a real cymbal, a breath, a vocal S, a guitar pick and genuine synth air all survive. Then it puts clean air back on top.

AnalysisSuno shimmer detected · High
Four modes
Pick a strength, or let it choose.
Natural
The recommended default. Removes artificial shimmer while keeping clarity.
Warm
More analog-style smoothing and a richer midrange.
Deep Repair
For heavily artificial generations with obvious metallic or fizzy texture.
Stem aware
It repairs the vocal without darkening the kick.
The song is separated first, shimmer is measured on each part on its own, and the restoration is applied where the problem actually is. Then everything is put back together. That beats processing the stereo master blindly, every time.
