  • Reverberation generating system for generating later part of reverberation from initial part of reverberation and method of generating the reverberation
    Patent number: 5818944
    Abstract: A reverberation generating system stores parameter data representative of a series of timings and a series of sound intensities for an initial part of reverberation, and calculates a series of parameter data for the later part of reverberation by using a return map of the proportional constant for time intervals of the initial part inversely proportional to the square of lapse of time so that the reverberation generating system stores the parameter data for the initial part only.
