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. It reduces the sibilance (words with sss or shh sounds, like ship, chip, sip, zip, or jump) of phrases so that. 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. To solve this difficult problem, SPL has developed a new circuit design that combines ease of use with natural sound characteristics and the highest level of technical performance. Keep in mind that I've not been involved with this stuff for a long time, so Steve and others may have different opinions.The SPL De-Esser is a highly specialised audio tool for removing undesired sibilant frequencies in a very simple and musical way without compromising the timbre and natural character of a voice. If you can reproduce it properly, I'd think your playback system is in pretty good shape. It is very hard to reproduce sibilance throughout the whole recording and reproduction chain, but I've heard many recordings which have sibilance and if it is handled without problem it can actually be a fairly pleasing sound to me. I don't know that sibilance by itself is a horrible thing.

Mastering cd's is something I have little experience with, but I'm guessing that sibilance is not as big a problem there since the traditional vinyl cutting issues do not apply. And I am not sure that sibilance is as much of a problem when mastering to cd as it is when mastering to record. Once again, I would think it depends on the nature of the program material and how carefully sibilance was dealt with during production. I don't know that digital recordings by definition have greater sibilance problems than analog recordings, though with the potential for higher dynamic range I guess it is possible.

Consequently, I think it is better to control excessive sibilance by the more traditional methods. It can also be used to smooth out high frequencies in other instruments such as hi-hats or. It has been my experience that using the accelerator limiter can be detrimental to good sonics, so I generally tried to avoid it whenever possibly. A De-Esser is primarily used to reduce sibilance in vocal recordings. Without this, the cutting amplifier can overload and cause all kinds of problems. This is somewhat similar to a normal limiter, but it is in the cutting amplifier's signal path. If there is too much high frequency content on the program the accelerator limiter can come in to play to limit the signal going to the cutting amplifier. It is much harder to cut high frequencies on a record than it is to cut lower frequencies. This is unfortunate as sibilance caused by things like esses or Ts can be an audio engineer’s nightmare.

In addition to this, most record lathes had what is called an accelerator limiter. De essing vocals is a highly underrated technique in mixing and many engineers don’t utilize it to its full potential. This is an oversimplification of how standard de-essers work. By boosting this frequency, the limiter can be triggered by the specific trouble frequency. The equalizer is used to dial in the frequency where the problem is. It is essentially the process of reducing the high-end frequencies in vocal recordings that often cause a piercing frequency spike when the vocalist makes a sss or shh sound. Click to expand.This can be handled by traditional signal processing by using de-essers, which is basically a compressor/limiter with an integrated equalizer. What is de essing De essing is an absolutely crucial part of vocal recording.
