R_WARE PORT OF AIRWINDOWS DeBess
AW_DeBess is a port of the Airwindows DeBess. The algorithms have been refined for the VM environment.
TL;DW: DeBess is an improved DeEss, with perfect rejection of non-ess audio.
DeBess is not for taking stage mics and making them lisp. It is very distinctly for taking the most high-end of vocal tracks and de-essing only the ess sounds out of them, with zero cost to anything else. Whatever you’re using, if your esses are blowing out the highest treble (which is exactly what you need a de-esser for) then it ought to work for you.
