| Well, I experimented with both a useDouble=0 version and a useDouble=1
version. The same csd provided these two results rendering to a file:
with useDouble=0 (ie, 32 bit):
CPU : 167 seconds
with useDouble=1 (64 bit):
CPU : 59 seconds
I suppose this makes sense, but it was contrary to my expectations.
It's nearly 3 times as fast to use 64bit internal samples under these
circumstances. These experiments were done with a macbook core 2 duo
(64bit) processor, osx 10.5 (64bit) and csound with Word64=1.
Thanks,
