Isn't it time we Pd's default sample rate to 48K? I don't think anyone else except Ableton Live is defaulting to 44100 any more.
I asked this a few years ago and I think Dan thought it was a bad idea, and so I punted for then. But I think someday we should take the plunge... are there still good reasons to wait on this?
My experience is that many built-in soundcards actually only support 48k, so Pd's default samplerate doesn't matter that much. Historically, probably because of this default setting, I've been creating all my Pd output with 44100. Not so long ago, but long after netpd has added support for the synchronization of audio samples, the impact of mismatching samplerates (between peers) came up and that it would give totally off results. I added a sr check in netpd and decided to declare 44100 as the standard sr for netpd in order not to break all existing saved sessions. But on the long run, it would be better to switch to 48k now, I guess.
The same for Pd. From what I can tell, 48k would be in accordance with most hardware that is around. Only Pipewire allows me nowadays to run JACK on built-in hw with 44100 although the hw only supports 48k (not an issue with external card that as a configurable clock). Everyone agreeing to 48k would be for the greater good, I'd say.
