Complete stereo reverb designed according to classic design of Moorer including early reflections (ref: "About This
Reverberation Business", James A. Moorer, Computer Music Journal, Volume 3, Number 2, 1979).
The essence of the algorithm (contained in a single block for convenience) is the combination of six comb filters and an
allpass filter which together produce the dense reverberations. A 7 or 19 tap FIR filter is used to produce the early
reflections.
