What it is
A targeted suppressor for the artifacts that show up most often in AI-generated audio: high-frequency shimmer (top-end "sparkle" that sounds wrong), low-mid fog (cloudy build-up that smears the mix), and pitch instability (micro-warbling, especially on sustained vocal notes). The suppressor is sensitivity-driven so it stays out of the way on clean material and engages only where the artifact crosses the threshold.
How to use it
- Enable the suppressor in the dynamics rack
- Strength sets the overall amount of suppression across all three artifact categories
- Shimmer Threshold sets how loud a treble artifact has to be before suppression kicks in
- Fog Reduction sets the amount of low-mid clean-up
- Pitch Sensitivity sets how aggressively pitch wobble is corrected
- Defaults are conservative; raise Strength gradually until the artifact is gone
What it affects
AI-generated tracks from Suno, Udio, and similar engines often have signature artifacts that listeners hear as "off" even when they can't name what's wrong. The suppressor leaves clean material untouched and engages selectively where shimmer or fog crosses the threshold. Pairs well with Surgical Cleanup for residual narrow-band resonances that the suppressor can't catch (it works on the broader spectral character).
