DIGITAL AUDIO LEVEL VARIABLE DEVICE

摘要

PROBLEM TO BE SOLVED: To eliminate a noise caused by a sudden level change. SOLUTION: A sampling means 2 samples audio level setting information set by a level setting means 1 for each main period and when a digital audio output means 4 outputs a digital audio output in response to a level of the main period sampling output, a smoothing means 5 smoothes a change in the main period sampling output so as to suppress a sudden change in the main period sampling output in the digital audio level variable device.
