Abstract: ENVIRONMENTAL EFFECTS GENERATOR FOR DIGITAL AUDIO SIGNALS An device and method of generating environmental reverberation effects for digital audio signals is presented. The device includes a reverberation controller. The reverberation controller pre-processes one or more predetermined characteristics of a first audio signal to produce a pre- processed signal and generates a plurality of delayed outputs from the pre- processed signal, each output having a predetermined delay. The reverberation controller also produces a plurality of reflection outputs from the plurality of delayed outputs and combines the plurality of reflection outputs to produce a second audio signal having a desired reverberation response.
