People say 32 bit is faster. I found that in a very few cases, I could easily hear differences between 32 bit and 64 bit renderings. I do not think these rare differences would be significant in live performance. It takes some work to be able to find and hear the differences!

I think in live performance, speed is important for most people, so unless sound quality is absolutely critical for you, I would use 32 bit samples.

Hope this helps,
Mike

For Csound5 in Windows, what are the pros and cons of 32-bit vs. 64-bit
builds for purposes live performance?

I concure with Michael on both counts. Mind you, I perform in night 
clubs with mismatched sound systems turned up way too loud, so it could 
be different in a pristine hall with properly balanced amplification. ;)

On Saturday during a performance, I made the mistake of using a double 
precision compiled Csound5 (csoundapi~) *WITHOUT* turning the 
processing priority of Csound all the way up while having the computer 
simultaneously output to dual-DVI video. Needless to say there were 
dropouts in the audio thread that could've been avoided ...

Really there doesn't seem to be that much of a difference IMO in 32/64 
bit precision samples. Because of discussion on this list I've tried 
several experiments to this end and really it seems like if the music 
is good, it will still sound good regardless of if it's rendered at 
single or double precision :)
