Claim:
1. An audio processing device, comprising: a first processor that cyclically counts a sampling clock to a first count value, and outputs an audio effect sound generated by processing a received audio waveform signal each time the count of the sampling clock reaches the first count value; and a second processor that cyclically counts a sequence clock to a second count value, and causes a corresponding segment of a preset music to be played each time the count of the sequence clock reaches the second count value so as to perform an automatic play of the preset music, wherein each time the count of the sampling clock reaches the first value, the first or second processor, or a separate circuit unit in the audio processing device detects a time difference between a time at which the count of the sampling clock reaches the first count value and a time at which the count of the sequence clock reaches the second count value a number of times corresponding to said time at which the count of the sampling clock reaches the first count value, and adjusts the second count value for a subsequent cycle of counting in accordance with the detected time difference so as to reduce the detected time difference, thereby providing synchronization of the output of the audio effect sound with the automatic play of the preset music over time.
