Abstract:
1. A parameter generating apparatus for generating a parameter for use in simulation of acoustic characteristics of an acoustic space in which elements including a sound emitting point for emitting a sound and a sound receiving point for receiving the sound emitted from the sound emitting point are placed, the parameter being used for processing an audio signal output from the sound emitting point to synthesize an audio signal to be received at the sound receiving point, the parameter generating apparatus comprising: a display control portion for displaying, on a display unit, a plurality of operational elements including at least a sound emitting point image representative of the sound emitting point and a sound receiving point image representative of the sound receiving point, and an acoustic space image representative of the acoustic space; a selection portion for simultaneously selecting a plurality of operational elements from among the entire operational elements in accordance with a user's operation; a transfer limiting portion for limiting a manner in which the simultaneously selected operational elements are transferred; a transfer determining portion for determining, when transfer of the simultaneously selected operational elements is instructed, a state in which the simultaneously selected operational elements are transferred on the basis of the instruction for transfer and the limited transfer manner; a display position modifying portion for modifying the position at which the simultaneously selected operational elements are displayed on the display unit on the basis of the determined transfer state; an acoustic space internal position modifying portion for modifying, on the basis of the determined transfer state, information representative of the position of operational elements placed in the acoustic space; and a parameter generating portion for generating the parameter on the basis of the resultant information modified by the acoustic space internal position modifying portion.
