imho, the only sensible place to do this is the actual audio backend

right
your audio backend might support double floats
(e.g. jackd is prepared for that already, though i don't known whether
anybody ever used it
Hey Katya,
I'm very happy you're working on this, I think its a big and very
valuable step for Pd for many reasons. For me, things like accessing
large arrays and also working with UNIX timestamps and other large
integers directly, make Pd a lot easier in cases that touch on those

like you've covered that already. As for 64-bit floats to output, a
quick hack to get things working is to just hammer samples down to

i don't think that's such a great idea.
Hi all --
I'm not sure it's done right, but my intention in s_audio_pa.c is to
use 'float' when talking to the portaudio API and t_sample to talk to
the rest of Pd -- so t_sample could be made double without affecting
portaudio.
The only situation I can imagine in which t_sample might want to

I think the big question that needs to be answered before this gets
included is:
can this be done without majoring impacting 32-bit operation?
The intention is:
- Pd source code with unaltered functionality
