Auto-Dynamic De-Esser 

The Auto-Dynamic De-Esser is a specialized audio tool for removing undesired sibilant frequencies in a very simple and musical way. The S-removal is based on phase cancellation which does not compromise the timbre and natural character of the recorded vocal track.

The Auto-Dynamic De-Esser uses a unique technology to reduce sibiliance in a mix or on vocal tracks. The result is a neutral, unobtrusive and extremely effective de-essing process. Even at high S-reduction values the de-essing has a negligible effect on the character and timbre of the voice. SPL has developed a new circuit design that combines ease of use with natural sound characteristics and the highest level of technical performance. 

The Auto Dynamic De-Esser monitors the entire frequency spectrum and automatically detects the sibilant frequencies. The bandwidth is set so narrowly around the range of the sibilance that neighboring frequencies remain unaffected. This frequency band is mixed back into the main signal phase-inverted to cancel out the sibilance. The result is a sound-neutral, inconspicuous and extremely effective process. Even at high s-reduction values the de-essing has an egligible effect on the character and timbre of the voice.
