NST Audio Dynamic Equalization

December 19, 2020

Dynamic EQ

Dynamic Equalization (DEQ) is essentially a compressor or expander that can be set to respond to and adjust the gain automatically over a certain range of frequencies. Its behavior is dependent on the mode chosen – two of these are relatively “traditional”, whilst two other modes offer the possibility to turn the normal action of compressors and expanders on their head introducing innovative adaptive control of the program material.

“Cut Above” Mode

This is one of the more traditional modes of operation. Having selected the frequency band to work with, the dynamic eq will “listen” to this band and act upon it by cutting (compressing) any frequencies present in it that exceed the threshold.

“Cut Below” Mode

Having selected the frequency band to work with, the dynamic eq will listen to this band and act upon it by progressively cutting any frequencies present in it that drop below the predetermined threshold.

“Boost Below” Mode

This mode operates in a slightly unconventional manner insofar as behaving as an ‘upwards expander’, as opposed to the more traditional ‘downwards expander’. What this means is that as the signal drops below the threshold, the selected band of frequencies will be progressively boosted in relation to the rest of the spectrum, offering a perceived ‘lift’ in the band.

“Boost Above” Mode

Arguably the most “dangerous” (!), this is the other unconventional mode of operation, offering upward expansion, where the signal is boosted once it reaches the threshold.
