3.4.3 Low Level EQ

The low-level path also has 1 configurable Biquad to establish the EQ curve the audio is sent through when the time average signal is at a low-level. This fully-functional Biquad can be assigned to several filter types. This determines frequency response when low-level is active based on the Energy configuration and the mixing thresholds.
