Abstract
An audio monitoring device includes a microphone for receiving sound energy from a loudspeaker, and a steganographic decoder that decodes the signal produced by the microphone. By reference to the steganographically-decoded information, the device can be used to monitor the musical selections played in a venue for copyright royalty purposes and the like.
