ABSTRACT:
An electronic sound enhancing system for improving the symphonic criteria of sound emanating from a performing shell is provided. Microphones are disposed in the performing shell for receiving sound emanating therefrom and converting same to an audio signal. Reverberant field loudspeakers are positioned with respect to the performing shell to produce low frequency reverberant field sound. Forestage loudspeakers are disposed proximate the shell for emitting sound representative of the early first reflections of the sound emanating from the performing shell. Time delay circuitry disposed intermediate the microphones and the reverberant field loudspeakers and forestage loudspeakers respectively apply the audio signal to the reverberant field loudspeakers delayed by a first predetermined interval of time and to the forestage loudspeakers delayed by a second predetermined interval of time.
