SPL DeEsser – the Revolution of S-sound Reduction.

The DeEsser uses a unique technology to reduce sibiliance in a mix or on vocal tracks.
It automatically detects and hones in on the sibilant frequencies leaving neighboring
frequencies unaffected. These S‑sounds are mixed back into the main signal phase-inverted to cancel out the sibilance. The result is a sound-neutral, inconspicuous and extremely effective process.
Even at high S‑Reduction values the de-essing has an egligible effect on the character and timbre of the voice.

How does the SPL Auto Dynamic DeEsser Work?

The Auto-Dynamic DeEsser has a new circuit technology that automatically adjusts to the S‑frequencies and narrows the bandwidth so that only the range of the S‑sound is processed and all neighboring frequencies remain untouched. The frequency band determined in this way is mixed back to the original signal in phase-inverted form, whereby the S‑sound is acoustically removed. The result is a sound-neutral, unobtrusive, but extremely effective way of working. De‑essing now has very little negative influence on the timbre of the voice; side effects such as twanging or lisping do not occur. In addition, time-consuming readjustment of the frequency settings is no longer necessary. The SPL Auto-Dynamic DeEsser combines efficiency with sound neutrality. By the way, you can also soften hard cymbal sounds or snares perfectly with the DeEsser Mk2.
