PROBLEM TO BE SOLVED: To provide an electronic sound volume device capable of ensuring an excellent operability by a remote controller, while arbitrarily setting the number of volume adjusting steps of a reproducer. SOLUTION: The device includes a means 371 for receiving an i-th common volume level Dgain[i] (1 to N) on a common scale of N steps, a means 373 for converting the level Dgain[i] into a j-th unique volume level Dvol[j] on a unique scale of (n) steps, and a means 372 for controlling an electronic sound volume on the basis of the unique volume. The converting means 373 is provided with a means for storing an offset between the level Dgain[i] and the level Dvol[j], a means for controlling at least one of the level Dvol[j] and the offset so that the received level Dvol[j] agrees with the sum of the level Dvol[j] and the offset, and the adjusting means adjusts the level Dvol[j] in preference to the offset.
