[Swiftb0y]

Fixes #11361

Huge thanks to @atskler for noticing the issue and reporting it to us and upstream, as well as @cannam for doing the actual hard work of fixing the problem.

I have issued a PR against upstream VCPK to update to rubberband 3.2.0

microsoft/vcpkg#30551

LGTM, Thank you.

@atskler Can you confirm that this change is sufficient?

Can you confirm that this change is sufficient?

First my distro/repo should update rubberband to v3.2, after that I can check it.

My distro will never get R3 so I built it myself:
https://github.com/breakfastquay/rubberband/tree/r3
git checkout v3.2.0
meson build && ninja -C build install
Had to move the two headers to /usr/include/rubberband/ though

My will get it as it is a rolling release distro.
Anyways will Mixxx require minimum Rubberband v3.2 as a dependency for building it?

No, the resulting sound will just not be mono-compatible with a lower rubberband version.

Ok than let's merge it. Thank you for all the testing.

Rubberband 3.2 is available for my distro so I built Mixxx and checked it and it solved the problem.
