Transport of Context-Based Information in Digital Audio Data
This paper introduces a technique to embed context-based information into an audio signal and to extract this information from the signal during playback. Context-based information can be any kind of data related to the audio signal, such as the lyrics of a song or the score of a piece of music. A typical application will display the extracted information. Techniques from lossy audio compression, especially MPEG-1 Layer II, are used to ensure inaudibility of the noise introduced into the audio signal by the embedded data. Another aspect of the work deals with synchronized processing of the context-based information. Applications for embedding text information and for extracting this information during playback have been implemented and are presented in this paper. A variety of tests have been conducted to study the embedding capacity of various audio signals and to verify inaudibility of the embedded information.:
