![]() ![]() SPL's Auto Dynamic De-Esser monitors the entire frequency spectrum and automatically detects the sibilant frequencies. This results in the familiar and undesired side-effects such as lisping and a nasal-sounding vocal. ![]() Processing therefore compresses the entire selected range, notjust the sibilant or S sounds. In addition to the threshold parameter used to set the processing level, there is a frequency controller for setting the center frequency of the process (with bandwidths generally up to 4 kHz). Traditional de-essers use compression techniques. This ensures even de-essing independent of signal level so any necessary compression may be applied post the de-esser. Differences in the input level caused by the varying distance to the mic, are compensated for automatically. Rounding out the amazingly simple control system is an automatic threshold-adjusting function. Even at high S-reduction values the de-essing has a negligible effect on the character and timbre of the voice. The result is a neutral, unobtrusive and extremely effective de-essing process. Input processed via this frequency band is mixed back into the main signal phase-inverted so that only the S-sounds are cancelled where the S-reduction controller determines the intensity of the phase-cancelled mix. The de-ess bandwidth is set so narrowly around the range of the sibilance that neighbouring frequencies remain unaffected. ![]() The SPL De-Esser monitors the S-frequency spectrum and automatically detects the sibilant frequencies. SPL has developed a new circuit design that combines ease of use with natural sound characteristics and the highest level of technical performance. Automatic threshold adjustment compensates for poor mic technique.Automatic detection of sibilant frequencies.Neighbouring frequencies remain unaffected.Preserves natural sound characteristics.The SPL De-Esser is a specialized audio tool for removing undesired sibilant frequencies in a very simple and musical way without compromising the timbre and natural character of a voice. ![]()
