| Abstract : | Abstract. Homomorphic signal-processing techniques are used to place information imperceivably into audio data streams by the introduction of synthetic resonances in the form of closely-spaced echoes. These echoes can be used to place digital identification tags directly into an audio signal with minimal objectionable degradation of the original signal. 1, |
