64 Bit will give computers more horsepower so to speak but I don't think It's going to change the math behind DAW summing. The software audio applications will still use the same algorithms to sum as far I know.

I agree with InfiniteArchitect. More horsepower is of course a good thing. But basically all the programs will do the same thing as before.

Of course, some time in the future, there will be advances in algorithms that necessitates having this extra horsepower. But to put it a bit pointedly, things are pretty good today, so the difference will not be a revolution. (Well, not every application out there is good, but that is probably more due to "lazy" programmers than to actual need of 64 bits).

THE Only application I know of the uses 64 bit summing is SAW studio It sounds great I don't know if it's the summing bus or what but several Mastering engineers use it ???? !!!

PS: PT is 48 bit , most others are 32 bit
