not much attention here, but here's an anser from the SC list about their discussion in porting the audio server to 64 bits
"
The biggest advantage of higher resolution is in things like filter loops, but most SC UGens already do 64 bit calculations internally where that’s appropriate"
I guess it makes sense, 32 bit is more than enough for dealing with audio signals/amplitudes.
So I assume Pd won't likely bother to become 64 bits like Max did for similar reasons, and maybe just think "internal 64 bit calculations" sooner or later, or does that already happen?
