When I said "64 bits sounds better," I had controlled tests that proved it. 

Also, I would say that saying X is "10% faster" or whatever means little outside of the actual context of performance. The question is not so much whether X is faster than Y, it is whether X is fast enough.

I propose that for live performance, "fast enough" means that on reasonably current hardware, Csound would be both (a) roughly as efficient as its competitors such as PD, and (b) efficient enough to do what performers want. My impression is that csound64 fits this bill.

I do recognize that a significant advantage in speed does open up new possibilities. What this means is, if I found csound32 was 3x faster than csound64, or even 2x faster, that would mean I could things with csound32 that I just couldn't do with csound64. In that case I would eat my words.

But I suspect we are not talking about this degree of difference.

I will be interested to pursue this issue further when there is more evidence.

Best,
Mike

I have a 64 bit machine, so I'm probably fine. But I intend my sets to 
be runnable on 32 bit machines, and I know that

a) in a night club, 64 bit will not sound noticeably better
b) it will, to some unknown degree, be slower on a 32 bit machine.

To what degree, I admit I don't know. I do know that many plugins on 
other systems do run slower if using high bit rates ( reverbs etc ). So 
I think it's unwise to force csound users to go 64 bit if they don't 
need to.
