The stereo widening CAO consists of the following features:
Stereo Widening effect AO – this provides the core effect
Sidechain path for bass – this provides a bypass path for bass to maintain punch and low frequency clarity
Sidechain path for difference signal – this provides mixing of the difference signal for enhanced width and space
Biquads for additional spectral tuning – this provides spectral balancing as needed; can also be used to tune in an elevation effect using the pinna response at different source elevation angles as a guide
