SPL has developed a circuit technology that combines efficient de-essing with maximum ease of use. Using the de-esser while recording can not only improve the quality of the recording, but also saves a lot of time compared to processing it later in post-production.
The SPL DeS automatically adjusts itself to the relevant frequencies and hones in on them so that only the range of the S-sound is processed, and neighbouring frequencies remain untouched. This range is phase-inverted and mixed back into the original signal, which acoustically deletes the S-sound. The SPL DeS therefore works unobtrusively and sound neutral.
The SPL DeS features our Auto-Threshold which automatically adjusts the threshold if the input level fluctuates due to varying distance to the microphone which leads to fluctuating input levels. With Auto-Threshold engaged, the de-essing intensity remains constant at the value you set – a great help not only for untrained speakers/singers in the studio and live.
With conventional de-essers using compressor technology, the processing intensity decreases as the distance to the microphone increases to which compressors or limiters then react by letting the S sounds reappear. The disadvantage of weaker de-essing – bad enough in itself – therefore also leads to undesired effects in the subsequent processing. Auto-Threshold prevents these disadvantages from occurring in the first place.
