Abstract
To provide a sound signal processing method capable of overlapping information with a sound signal without being influenced of various kinds of communication paths.SOLUTION: A sound signal processing method includes steps of: determining a predetermined reference input value, and calculating a relative input value in response to the reference input value from an input object data; receiving a sound signal and overlapping the reference input value into a first frequency region of the sound signal; and overlapping the relative input value into a second frequency region and outputting the sound signal after the overlapping.SELECTED DRAWING: Figure 4
