Hi.
Raspbian is now called Raspberry PI OS.
And a full 64bit Beta is available.
Finally. A 64 bit version.
Having a full 64bit version - kernel and userspace - are good news for us RPI4 owners.
I'm running my own 64bit Arch Linux since quite some time. It works really well.
These folks who run e.g. Moode can look forward to it, if of course Tim and the other OS folks decide to go for it. Maintaining a 64 and a 32 bit version could mean a lot more effort to them.
Enjoy.

Hi soundcheck,
And, then the guy with the stupid question: I have a Raspberry PI 3b, is it also for me?
Regards,

Yep. RPi 3 and 4.
As you might know 64bit kernels are available already on most of the
distros out there.
Meaning. Currently most of you can and many do run a 64bit kernel and a 32bit userland.
The key change towards RPiOS is to introduce the 64bit userland.

One key issue with ARM based systems for audio processing beyond going 64 bit still remains the lack of NEON support within many of the applications out there.
NEON support (NEON an ARM CPU feature) accelerates the processing of audio (and video) data substantially.
There's hope though.
There's e.g. a flac project for NEON and 64bit support ongoing. I've been talking the other day to the flac designers about it and I've been testing a prototype.
There's still some work to do. They are on a good way though.
First tests show 100% performance improvement. That's promising. And that also explains why x86 based systems perform
much better on that account. Many of the x86 CPU acceleration features (SSE etc) are already in place.
Bottom line. A 64bit userland is not the only thing we can look forward to. There's more to gain. 😉
