Dynamic speaker management for multichannel audio systems

摘要

A multiband limiter with selective sideband linking includes first and second frequency band splitters, a first and second plurality of limiters, first and second summers, and a plurality of selectable links coupling the first plurality of limiters to the second plurality of limiters. The first plurality of limiters each have a band input coupled to one of the first plurality of band outputs, a link port and a limiter output, and the first summer is receptive to the limiter outputs of the first plurality of limiters and has a first channel output. The second plurality of limiters each have a band input coupled to one of the second plurality of band outputs, a link port and a limiter output, and the second summer is receptive to the limiter outputs of the second plurality of limiters and has a second channel output.
