Abstract
A device for audio signal processing includes a main processor and two audio processors electrically connected with the main processor. Each audio processor corresponds to a channel of a stereo audio output. The main processor provides an indication signal for the two audio processors. Each audio processor generates a synchronization signal according to the indication signal and performs audio signal processing according to the synchronization signal. The synchronization signals begin simultaneously and have the same frequencies that equal a sampling frequency. Each synchronization signal includes at least one pulse, and a start of each pulse of each synchronization signal is aligned in time with a start of a pulse of the indication signal. The audio signal processing performed by each audio processor begins at an end of one of the at least one pulse in the synchronization signal corresponding to the audio processor.
