Abstract
An audio signal data processing system includes first and second processing devices for processing audio signal data, the first and second processing device having input and output ports of at least two channels, and a control device for controlling the operation of the first and second processing device. The input audio signal data is supplied to the input port of one channel of each of the first and second processing devices, and output data from the output port of said one channel of said first processing device is supplied to the input port of the other channel of the second processing device, and output audio signl data are obtained at each output port of both channels of the second processing device. With this arrangement, one of the cascade processing and the parallel processing can be selectively performed without using a change-over switch provided outside the system.
