Overview
What is Lisp?
Lisp - An efficient audio plugin that uses the Sleepy-Time Records transient detection algorithm to rid you of the unwanted sibilance effect
In depth
A closer look at Lisp
Lisp is a well designed and engineered de-esser plugin that enables users to clean up sibilance problems that can occur during music production or recording. The plugin uses sibilance detection algorithms that automatically detect and lower the unpleasant "ss", "teh" and "ch" sounds. It does so by tracking the amplitude and pitch in real-time.
