Note: until the sound file updates branch with the CAF file support is merged, 64 bit sample indices aren't yet useful with the current core file formats (WAV, AIFF, SND) as they use 32 bit indices.

Hi there, it's known Pd can be built with 64 bits precision, but when can we expect it to also be available for download as such?
I'm currently working on externals that play large files without running into precision issues, but that'd be unnecessary once Pd 64 bits is more of a thing.
It seems to me all should be good to go once it's already possible for those who compile it like that... so I guess the main issue would be with externals that also need to be compiled for that.
cheers

Cool, thanks!

Dan, is this in any way related with buffer indexing? I am wondering if with 64bit Pd the B16.long-varispeed.pd workaround with the second inlet will still be necessary to get cleaner table playback at slow speeds?
thanks, P
Double precision Pd indeed solves the table playback issue (among other things).

PS: "64-bit Pd" usually means Pd compiled for a 64-bit architecture, but this thread is really about double precision Pd. I'm sure you were talking about the latter, but this is a constant source of confusion, so I thought I'd better make this clear for other readers.

so, here I ask, could we expect a 64 bit precision Pd for download in the next release if that PR gets in? Is it just waiting to be merged, now?

It should be named dppd to avoid confusion imho.

or pddp (or is that already taken?)
when csound switched to double precision they renamed things to "csound64" (with "things" being at least the libraries that hold the engine).
so i like pd64 better, as it is obvious that this is still Pd (and not just some nice palindromic acronym).
but anyhow, yes: we probably need a catchy name.
