Abstract

In accordance with embodiments of the present disclosure, a method for operating a playback path comprising a first dynamic range enhancement subsystem and a second dynamic range enhancement subsystem, wherein an audio signal generated by the first dynamic range enhancement subsystem is communicated to the second dynamic range enhancement subsystem, is provided. The method may include determining a first operating parameter of one of the first dynamic range enhancement subsystem and the second dynamic range enhancement subsystem that affects behavior of the other of the first dynamic range enhancement subsystem and the second dynamic range enhancement subsystem, communicating a control signal between the first dynamic range enhancement subsystem and the second dynamic range enhancement subsystem indicative of the first operating parameter, and setting a second operating parameter of the other of the first dynamic range enhancement subsystem and the second dynamic range enhancement subsystem in response to receipt of the control signal.
