OTOH, if the 'studio' setup is not trivial and being used every day,
then you probably have a script or something else to set it up, and
having to resstart from 'cold and dark' is not a big deal.
One very practical reason for running the studio at a fixed sample
rate is having ADAT interfaces for example, which reduce to four
channels at 96 kHz. One way to do that is using a 'resampling'
Jack backend which is itself a Jack client.
A world of exhaustive, reliable metadata would be an utopia.
It's also a pipe-dream, founded on self-delusion, nerd hubris
and hysterically inflated market opportunities. (Cory Doctorow)
