Digital multieffects processors is a useful tool to study and demonstrate room acoustic parameters. Live and prerecorded speech and audio program will be processed through a multieffects device and reproduced through a pair of loudspeakers. The listeners will be allowed to hear the effect of varying a number of acoustic parameters that occur in natural spaces. These include: reverberation time, echoes, diffusion of sound, high frequency decay rate, initial time delay gap, spaciousness, and depth. A brief explanation of each parameter will be given before its audible demonstration. The means in which an architectural acoustician designs an acoustic space with these parameters in mind will also be discussed.
