Yeah, looking forward to bringing that to [community] actually! :)

Well, if you're looking at professional studios, they don't record below
a sampling rate of 96kHz usually.
To get that kind of throughput stable might require quite some
experimentation depending on your hardware.

That is to say: I'm also not up for adding a specific preset layer to
Arch. Acquiring realtime-privileges and enabling the user to tune
his/her system is much more viable, as the exact implementation will be
very diverse and depending on the hardware or the user's software.
Or as Ralf said: Best case, you won't even have to change anything at

However, I think that we can and should improve our relevant wiki
entries (e.g. [1]).
