The MCDSP DE555 Advanced De-esser Native is a new generation of de-essing technology, providing transparent, precise de-essing with unique flexibility. The intelligent signal analysis allows the DE555 to effectively de-ess at any signal level – no manual input threshold adjustment required. Other options include continuously adjustable ratio and release controls to fine-tune the de-essing amount, plus a high frequency (HF) only mode for reducing the signal level of only the ‘sss’ and not the original dialog.

Key filter options include high pass and band pass filtering. A unique focus control further enhances the key filter’s ability to separate ‘essing’ from actual dialog. The key filter output can also be monitored. Real-time displays of de-essing amounts and key filter response enable a quick and easy setup.
Reducing Sibilance
More aggressive de-essing settings for background vocals allow the lead vocal to stand out more, as the lead vocalist articulation comes out, while the background vocals remain, well, in the background.
When using DE555 HF only mode, the frequency shift control will move around the HF only processing as much as one octave below or above the selected key frequency. Very useful for attenuating different frequencies other than the original key frequency.
Smooth Guitar Tone
Fret squeaks produced by the guitar player can be reduced using a de-esser. The same tips apply when de-essing a vocal or dialog track – too much can sound unnatural – so don’t overdo it.
