PURPOSE:To attain an effective signal processing by providing a means which performs the audible display of an output from a digital/analg signal conversion means. CONSTITUTION:A signal on which a prescribed signal processing, is applied at a digital signal processing equipment 6, when it is requested to be evaluated, is stored at a digital signal memory device 5, and is inputted to a digital/analog signal converter 3 through a digital signal path 103, a digital signal selection equipment 1, and a digital signal path 104, then being converted to an analog signal. Therefore, it is displayed as an actual sound with an audible display device 7, and an operator can evaluate and recognize it. Also, even when a sample (original signal) on which the signal process is requested to apply is the analog signal, the process at a digital signal area can be performed by transferring it to the digital signal processing equipment 6.
