PROBLEM TO BE SOLVED: To provide a process schematic diagram display device enabling to rapidly find a module having improper parameter when a fault occurs in an audio signal, and to provide a program. SOLUTION: An algorithm of an apparatus for performing audio signal processing is displayed as a block diagram shown in Fig. 5 by combining various software modules such as a filter, a router and a mixer. Usual connecting lines 250, 280 for connecting between blocks are shown with "large solid lines". A connection line 270 having an output level smaller than a predetermined value is shown with a narrow line. A connection line 260 indicating mute (silencing) audio signal is shown with a dotted line. When parameters of modules are edited on the block diagram, related connection lines are re-drawn on the basis of a result of editing. In this case, in the case where an audio signal to be output from a mixer is in a mute state, a module as a cause of the mute signal can be rapidly specified. COPYRIGHT: (C)2008,JPO&INPIT |
