How did you succeed in reducing the time delay in version 2 of the 8400s DSP software?
Delay in version 1 came from two separate sources: irreducible delay caused by the 8400’s sophisticated look-ahead algorithms, and reducible delay caused by various “housekeeping” functions like filter delays. By rigorously examining every reducible part of the delay, we were able to greatly reduce it without compromising the operation of the look-ahead algorithms that give the 8400 its uniquely favorable loudness/distortion tradeoff. Some of the techniques we used included parallelizing certain algorithms and running more of the processing at higher sample rates.
