Patent ID: 8156433

Claim:
An embodied music system, creating an interactive interface between a listener and the external environment, the system comprising: a physical device located in the environment and providing sensory input to the listener; an audio signal adapted to be heard by the listener; an encoder embedding control data inaudible to the listener into the audio signal using high frequency temporal coding, adding to the audio signal a high-frequency carrier signal, the encoder including (a) a frequency-domain filter adapted to clear all frequencies of a fast Fourier Transform analysis of the audio signal above about 15 kHz and create a filtered file; (b) a summation device adapted to sum the filtered file, after the filtered file has been returned to a time-domain signal, with the control data as embedded into the carrier signal to create a sound file; and (c) means for recording or storing the sound file; a decoder extracting the control data from the sound file and transmitting the control data to the physical device, thereby controlling operation of the device; and an audio reproduction device connected to the decoder and playing the audio signal for the listener, whereby the listener experiences multi-sensory compositions.
