1. A system for processing audio data to enable enhancements to the audio data, the system comprising:
- an audio receiver operative to receive a watermarked audio signal, the watermarked audio signal comprising an enhanced audio signal and a digital watermark configured to indicate the presence of the enhanced audio;
a watermark detector operative to;
detect the watermark in the watermarked audio signal, andprovide a control signal to an enhancement decoder portion of an audio decoder in response to detecting the watermark in the watermarked audio signal; and
the enhancement decoder portion of the audio decoder operative to process the enhanced audio signal with an audio enhancement in response to receiving the control signal.

7. A method of identifying a sound enhancement technique in an encoded audio stream, the method comprising:
-
receiving an enhanced audio signal, the enhanced audio signal comprising an embedded watermark operative to identify an audio enhancement process used to encode the enhanced audio signal; analyzing the enhanced audio signal to detect the presence of the embedded watermark; providing the enhanced audio signal to an audio decoder; and activating an enhancement of the audio decoder, said activating configured to cause the audio decoder to process the enhanced audio signal with the audio enhancement. - View Dependent Claims (8, 9, 10, 11)
