Artificial reverberation is added to sound signals requiring additional reverberation for optimum listening enjoyment. This paper describes methods for generating, by purely electronic means, an artificial reverberation which is indistinguishable from the natural reverberation of real rooms. This artificial reverberation can be given any desired characteristics to match different types of music and personal tastes. A method for making the artificial reverberation -ambiophonic- (i.e. , three-dimensional) is also described.
