Convex Optimization in Audio Reverberation
Given this industrial-strength reverberator topology, it is an open question to derive a method for choosing delayline lengths such that perceived decay is exponential. In layman's terms, it is difficult to choose delayline lengths that will not cause undulation in this reverberator's decay-tail in response to an impulsive input.
Choice of delayline length is an optimization problem because one must simultaneously insure that the network provides good musical qualities; e.g., a good reverberator should provide little coloration (input spectral change).
