Abstract
Apparatus is provided for processing a switched audio signal output received from a crosspoint router having a plurality of inputs and a plurality of outputs, there being a control signal that defines which of the plurality of inputs is to be routed by the crosspoint router to which of the plurality of outputs. A control unit receives the control signal and serves to identify a route change in the control signal. An instantaneous value of the switched audio signal prior to the route change is stored. A signal processing unit then combines the stored value with values of the switched audio signal after the route change to form a processed audio signal that changes smoothly.
