Real-Time Audio Watermarking System Prototype

A real-time audio watermarking system is presented. System contains two circuits: the marker circuit and the detector circuit. Watermark detection is blind, so, there is no necessary original signal to detect embedded information. Watermark detection does not need a synchronization stage; therefore, detection is carried out on any time. Both, marker and detector are implemented in a commercial digital signal processor starter kit from Texas Instruments and are fully host-independent
