A method and apparatus for increasing perceived reverberant field diffusion in systems providing electro-acoustic reverberant enhancement to rooms or spaces includes independent modulation of the phase of each individual release loudspeaker channel in response to an effectively random infrasonic modulating signal, independently developed for each channel. Each loudspeaker release channel is fed from an electronic reverberator. The release channel signals are timed to emerge into the room at different times. The amplitude of each channel may also be modulated. In one embodiment, independent devices for generating infrasonic modulating signals have the characteristics of at least two frequencies being present within the range of about five seconds/cycle to about five cycles/second, for supplying control signals for achieving modulation in phase and amplitude.
An apparatus for increasing perceived reverberant field diffusion, comprising:
An apparatus for increasing perceived reverberant field diffusion, comprising
An apparatus for increasing perceived reverberant field diffusion, comprising
A method for increasing perceived reverberant field diffusion in an electro-acoustical reverberance enhancement system, said system having reverberation imparting means, a loudspeaker release channel receiving a reverberated signal from said imparting means, for releasing sound signals, and a loudspeaker responsive to said release channel, comprising the step of independently, randomly modulating the phase of the reverberated signals delivered to said release channel with infrasonic modulating means prior to releasing said sound signals from said loudspeaker.
