SPL 9629 Auto Dynamic De-Esser


The SPL Auto-Dynamic De-Esser is a highly specialised audio tool for removing undesired sibilant frequencies in a very simple and musical way without compromising the timbre and natural character of a voice. To solve this difficult problem, SPL has developed a new circuit design that combines ease of use with natural sound characteristics and the highest level of technical performance. SPL’s Auto Dynamic De-Esser monitors the S-frequency spectrum and automatically detects the sibilant frequencies. The de-ess bandwidth is set so narrowly around the range of the sibilance that neighbouring frequencies remain unaffected.
