Receiving Data Hidden in Music

This paper presents a method for transmitting data within music played from loudspeakers. The data is hidden in the music by leveraging the psychoacoustic masking effect, so that humans are not disturbed by the data transmission. The system achieves data rates of over 900 bits per second. The client side of the system could be implemented as a smartphone app, which receives data wherever users are without requiring any setup, making the system user-friendly.
