ToneBoosters already provides two de-essers; the TrackEssentials de-esser with zero latency, and an integrated de-esser in TB Evoke. Both plugins have their own merit, but we thought we should be able to do better. New TB technology, such as ultra-transparent gain processing and tonal decomposition (as featured in the recently overhauled TB BusCompressor), the matched-filter technology from TB Evoke, and a couple of new innovations together result in a much better, powerful and transparent de-esser.
