Abstract:
1. An electronic device to generate artificial reverberation, comprising: a signal processing engine that, when viewed in the time domain, convolves an input signal with an impulse response representing acoustic space; a synthesizer communicatively coupled to said signal processing engine, said synthesizer to provide to said signal processing engine, when viewed in the time domain, a definition of said impulse response, said synthesizer comprising a first random number generator and a first density generator to provide, when viewed in the time domain, a first sequence of randomly spaced spikes, said synthesizer further comprising, a second random number generator and a second density generator to produce, when viewed in the time domain, a second sequence of randomly spaced spikes, wherein, said first and second sequences of randomly spaced spikes have, when viewed in the time domain, decay envelopes and maximum spacings between spikes that are user defined and customizable, wherein each of the signal processing engine, the first and second random number generators and the first and second density generators are constructed with electronic circuitry.
