smart:deess Content-Aware De-Esser from Sonible creates a more natural and balanced sound than most commercially available de-essers. By harnessing the power of a fully trained neural network, smart:deess identifies the exact start and end points of phonemes without the need to set a threshold. By analyzing the signal’s actual content, not just the level of one frequency band, smart:deess allows you to spend time on getting the sound you want, rather than correcting the sound you don’t want. Using spectral processing, smart:deess works in real time to process the entire sibilant, which helps make the final result far more natural sounding.
