Mastering VPI's  -  DynamicEQ

DynamicEQ provides dynamically controlled equalization within three separate frequency bands. As you adjust an EQ setting for a single band, the dynamic control analyses the degree to which these settings should be applied to the signal. It is possible to boost and cut up to 20 dB, while you can choose three different filter characteristics for each band. The dynamic stage offers the typical parameters - "threshold", "ratio", "attack" and "release" - for fine-tuning the dynamic analysis in each band. It works much like a compressor for controlling the amount of applied equalization.

An additional SideChain within the dynamic stage can be used to change the level of a dedicated frequency range within the analyzed audio signal. The "Gain Meter" displays the applied amount of equalization, while the adjusted EQ curve is visualized in the transfer function display.

The DynamicEQ can be used for multiple applications. In mastering for example, an EQ setting might only affect the quiet parts or specific instruments of a mix, while the loud areas are not affected. For restoration applications, it is possible to reduce ringing effects of old recordings without affecting softer parts without ringing. DynamicEQ can also be used for the correction of tonal imbalance on single musical instruments and voices. Intelligent De-Essing can be facilitated using different filter bands - while the first band is working very fast on sibilant peaks, a second one is running with smoother and wider settings.
