>Lucasfilm's sound processor at 1983 had fixed 1.5 ms latency. they probably had h/w that processed stuff sample-by-sample, rather than using block-oriented processing the way that general purpose computers do it.
if you want to match a sample-by-sample design for day, ProTools TDM h/w has a 1-3 sample delay, no matter what the DSP load. --p
