Methods of processing audio to convey auxiliary control information therein without audible evidence of data alteration. Various arrangements are disclosed. One receives plural bit auxiliary data in which the auxiliary control information is included, and modulates same with noise data to yield intermediate data. The intermediate data is then summed with the original audio to produce the encoded audio. The noise can be tailored to enhance performance, and the intermediate data can be scaled in amplitude so as to better hide the auxiliary data within the audio. One application of the technology is in consumer audio appliances, where the auxiliary control information can be used to trigger some response in the appliance, such as enabling or disabling certain operations.
