Spectral Lemuring by Fugue State Audio

Spectral Lemuring is, as the name implies, a spectral processing effect which is inspired by a discontinued freeware plugin with a similar name. The feature set isn’t exactly the same, but like the plugin that inspired it, it can process the high-magnitude and low-magnitude parts of the FFT signal separately, and can also „freeze“ the signal.

Put simply, it’s a lo-fi pitch shifter with some extra functionality.
