I think 64bit (double precision) throughout the chain guarantees for lowest
losses. The more you calculate the worse it gets. What does it help to run
your plugins ( e.g. libsamplerate) at 64 bit if the results get cut off
later on.

Come on. You're always striving for the best. You provide the best audio
engine I came across and then your come up with "and this would be harder to
implement " and "it should
do for most of the people".

64 bit throughout the chain is IMO the way to go to bring losses down to the
absolute minimum. OSX/MS DAWs are ahead of us here - that's bugging me at
