Gain change can take place either side of this band depending on the Trigger mode selected: in Above mode, dynamic gain change takes place when the signal is above the threshold, while in Below mode, the gain change is applied when the signal falls below the threshold. Both Sides NowĪs with most dynamics plug-ins, the point at which gain reduction in each band kicks in is set using a Threshold control. In most respects the GUI follows the typical Sonnox Oxford template and includes a Preset Manager that allows your presets to be called up in any host application. Sonnox Oxford Dynamic EQ is authorised to a second-generation iLok key and supports Audio Units, VST and AAX Native plug-in formats, and there’s also a UAD2 version. Sonnox have incorporated this characteristic into their five-band dynamic EQ, in a design based on their Oxford EQ’s Type Three gain/Q dependency. By contrast, many equalisers exhibit ‘proportional Q’ response, where the bandwidth narrows with increasing gain or attenuation, and this can often sound more natural. A multiband dynamics processor also differs from typical dynamic equalisers in that as the amount of boost or cut increases, the bandwidth remains constant. The crossovers used in a multiband compressor can introduce unwanted and audible phase shifts, and a parametric EQ is more ‘tuneable’ than a simple band-splitting system if necessary, EQ bands can also be made to overlap.
Multiband compressors use crossovers with a slope that is usually fixed, even if the crossover frequency is variable, and process each of the resulting frequency bands separately before recombining them, whereas a dynamic EQ applies the gain change directly to the gain parameters of a multiband parametric equaliser.īoth designs have their pros and cons.
Their roles do overlap to some degree, and both work by splitting the signal into multiple frequency bands, but they aren’t identical. The difference between a multiband compressor and a dynamic equaliser is subtle and sometimes misunderstood. As we’ve come to expect from Sonnox, their take on the dynamic equaliser boasts more than a touch of class.
