VOX Doctor is an extremely "musical" vocal de-esser and enhancer designed for use as an effect INSERT on MONO vocal tracks. In contrast to most sidechain based processors, VOX Doctor is NOT a compressor and will not alter the dynamics of the vocal.
VOX Doctor is a spectral balancer that limits the high frequency energy in the audio. When a vocal becomes excessively sibilant (as determined by the THRESHLD control) VOX Doctor steps in and reduces the high frequency content only as much as needed to level the spectrum. The processor will not produce "lisp-ing" or reduce the brightness of the audio. The actual audio being removed can be heard by using the "mode" switch on page 2 (INVERT mode). This tool is a necessity for any studio working with vocals.
