chroot might be an option, but this could cause a lot of unneeded issues
and I guess a virtual machine can't be used, at least I don't know how
to ensure that this emulates the real behaviour, when using professional
audio cards etc.. If there e.g. is jitter, is it caused by the
visualisation or is it regarding to the real hardware and drivers?
For a DAW you're dealing with HPET, timer resolution is 1000000000 Hz,
expected jitter for e.g. hw MIDI is far below a millisecond.
