One embodiment provides a system, method, and device for utilizing inaudible tones for music. A song is initiated with enhanced features. A determination is made whether inaudible tones including information or data are associated with a portion of the song. The associated inaudible tone is played. Playback of the song is continued.

Systems and methods for structuring information include determining information quantity (IQ) and information value (IV) in an original digital information file (ODIF). An initial manipulation process applied to the ODIF forms a first resulting DIF (FRDIF), and a subsequent manipulation process applied to the FRDIF forms a second resulting DIF, wherein each manipulation process removes at least one element of the processed DIF and/or represents an element combination with a representative element and a first indicia of an interrelationship between the representative element and one or more elements in the combination, to reduce the IQ of the processed DIF, while retaining the IV thereof within a threshold. Manipulation processes are successively applied to the previously resulting DIF until successive applications do not achieve a threshold reduction in IQ. The last resulting DIF has a primary structure with a reduced IQ and an IV within the threshold of the original IV.

Provided is a terminal apparatus including a target data acquisition unit configured to acquire target data which is: superimposed data obtained by superimposing spread encoded data on non-spread encoded audio data, the spread encoded data obtained by encoding information using a spreading code; or data obtained by converting sound reproduced on the basis of the superimposed data into an electrical signal; and an information extraction unit configured to retain multiple spreading codes and extract the information from the target data using a spreading code selected by a user.

A method comprises providing an audio file comprising two or more discrete tracks; separating the two or more discrete tracks; setting a limit on an amount at least one of the two or more discrete tracks may be altered; and outputting the separated and limited discrete tracks as a file for use by an end user.

In one example, a device for creating an event-driven audio file may comprise a processor and an audio engine to, when executed by the processor, receive a configuration file designating a number of device-external data feeds and create an event-driven audio file based on the configuration file. In an example, a method of creating event-driven audio may comprise creating, with a processor, a configuration file, the configuration file comprising links defining device-external data feeds and with an audio engine, parsing the configuration file, and, based on the data defined in the configuration file, creating an event-driven audio file.
