A constant balance volume control may include two 2nd order biquad filters that are controlled in a continuous manner by the volume control of a system. The filters could be implemented in analog or digital form.

  • Dynamic surround channel volume control
    Patent number: 8452028
    Abstract: A dynamic surround channel volume control applies a variable gain control to the surround channels of a multi-channel system. Thus the levels of the surround channels are related to the main volume control of the system. This maintains a predictable relationship between the surround channels and the main or front channels.
