Abstract
Level detectors detect levels of digital audio signals of individual channels. A controller predicts whether or not an overflow will take place corresponding to detected signals. When the controller predicts an occurrence of an overflow, attenuators attenuate a signal level of at least one channel. In addition, when variable length delaying devices vary the phases of signals, an overflow can be prevented.
