Sleepy-Time DSP releases Lisp (Level-Independent Sibilance Processor) for Windows VST (Free)
Sleepy-Time DSP, formerly Sleepy-Time Records, has released Lisp (Level-Independent Sibilance Processor) for Microsoft Windows 32-bit and 64-bit systems in the VST2 and VST3 formats.
Lisp is a de-esser that works regardless of your audio's input level and requires no frequency setting. Simply set your reduction amount and Lisp will automatically detect the "ess" sounds in your audio track, turning them down with highly transparent results.
Lisp is available for free at http://sleepytimedsp.com/software/lisp/
