The threshold level level of the adjustable processing band is shown alongside an FFT display of the frequency band of interest, which has a peak-hold facility to make troublesome sounds more visible, and when gain reduction is applied, the spectral change is shown in red.Īpparently, the gain control element of the SuprEsser is a modified version of the compressor section of the Oxford Dynamics plug–in, teamed with a pair of linear–phase crossover filters, so that the compressor acts only on frequencies in the range that needs treatment and applies gain reduction via a tuneable band–reject filter. A red vertical pointer continually follows that part of the spectrum where the energy is highest. Operation is simplified by a very slick graphical display, which makes it easy to pinpoint frequencies that need treatment. It can also be applied to removing low–frequency thumps from improperly recorded vocal parts, and some users have found applications for it as a general–purpose dynamic equaliser. It is a very sophisticated de–esser based on a frequency–specific compressor that targets only that part of the spectrum where problems occur, and is adjustable to cope not only with vocals but also the unwanted whistles associated with some types of wind instrument.
Sonnox oxford plugin review Pc#
The Sonnox Oxford SuprEsser is available in native formats across both Mac and PC platforms to support RTAS, AU and VST–compatible hosts. Those that reduce the level of the whole signal can make vocalists sound as though they are lisping, so the more elegant de–essers act either on frequencies above a certain crossover point, or on a restricted band of frequencies corresponding to the part of the audio spectrum where sibilance occurs. Sonnox are the latest manufacturer to apply some new thinking to the humble de–esser.Ī de–esser is, at heart, a specialised compressor that reduces the level of part or all of the audio signal when a sibilant high–frequency event, such as an excessively pronounced 'S' or 'T' sound, is detected.
