2.2.5 DPEQ

The dynamic parametric equalizer is used to mix the audio signals through two signal paths (low level and high level). These two paths are used with separate equalization properties. A third path monitors the incoming audio and determines the thresholds and mixing characteristics between these two paths. Thus, the mix between the two high- and low-level channels is dynamic in nature and depends on the incoming audio. Refer to Section 3.4 for more details.
