Explains the principle in depth.
Overlap-add is a very useful technique in DSP. However, it is
completely orthogonal to the FIFO buffering required in any plugin
that involves latency. You can skip overlap-add, but you'll still
need a FIFO. But you cannot skip the FIFO just because you implement
overlap-add.
At this stage, I think that Mark doesn't need to consider overlap-add
unless it's already part of his algorithm. It just makes his problem
more complex to include overlap-add on top of all the other
considerations.
