摘要： An arbitrary signal insertion method and an arbitrary signal insertion system, capable of inserting a transmittable arbitrary signal (insertion information M) at a predetermined insertion timing into an acoustic sound played in real time. An insertion timing is previously associated with a predetermined time code with master rhythm information. An acoustic sound into which insertion information will be inserted is music sound generated by a real-time performance unit and is accompanied by a second rhythm. The insertion information is inserted into the music sound generated by the real-time performance unit at the insertion timing after the rhythm of master rhythm information and the rhythm of the music sound generated by the real-time performance unit are synchronized. The synchronization is achieved by a rhythm transmitter which notifies a player of a rhythm session musical instrument of the rhythm of the master rhythm information with sound or light.

摘要： To provide a transmission method of an arbitrary signal using an acoustic sound hardly affecting the mood (quality) of the original acoustic sound even if an arbitrary signal within an audible frequency range is combined into the acoustic sound such as music.The method comprises a step of finding a separable sound, of which a fundamental element (fundamental sound) b2 contributing mainly to recognition of a single sound and an additional element contributing collaterally to recognition of the single sound are separable on temporal axis or frequency axis, among plural sounds composing the acoustic sound, or inserting a separable sound into the plural sounds composing the acoustic sound. The additional element of the separable sound found or inserted is transcribed by a signal pattern b1-1, b1-2 of the arbitrary signal. By means of the acoustic sound of which additional element is transcribed, the arbitrary signal b1-1, b1-2 is transmitted. The additional element may be a sound generated when transmitting vibration energy to a resonance body (resonant body). The fundamental element may be a sound produced according the own resonance mode (resonant mode) by the resonance body (resonant body) receiving the vibration energy.
