Equalizer Nominal and Center Frequencies

Center Freq (Hz) 1 octave band

These band edges are exactly between the center frequencies. At the band edges, the gain of the equalizer

band is half the gain (in dB) at the center frequency. Adjacent bands in the graphic equalizer bleed over into

each other and affect each others' total gain which can increase the amount of time a user must spend

adjusting the equalizer to arrive at a desired frequency response. The graphic equalizer provides a gain

compensation control that corrects the gain settings of each band to provide the desired gain specified by

the user at each center frequency.

Processing Delay

The delay processing allows the designer to add from 0 to 1000 milliseconds of delay on the output

channels. While the delay is set in milliseconds in the user interface, it can be manually set through the

command API in samples where each sample represents 1/48 of a millisecond.

This section describes the processing that is available for each submix channel. Submixes may be defined

as mono virtual channels or stereo virtual channels. When the submix is a stereo virtual channel, the

processing is applied equally to both the left and the right physical channels that define the stereo virtual

channel. Each time a signal is sent to a submix and received back into the matrix, 1.5 msec is added to the

delay of the signal.
