AUConverter and the Output units we ship can have different sample
rates.
AU3DMixer can have different sample rates on its inputs - it uses a
cheap linear rate converter to deal with the discrepancy
AUVarispeed and AUTimePitch can have different sample rates on input/
output
Effects and instruments must have the same sample rate.

Hi,
Is it possible for an apple's au mixer unit to handle multiple
au converter units which are converting different sample rates into
a 441000 and inputing those frames of audio into the mixer, and
lastly sending these frames to the default output unit? My recent
design and implementations are telling me this is not possible. I
can have multiple inputs to a mixer with the same sample rate where
all units in the design and chain must have the same sample rate.
Actually, it appears that all au's must have the same sample rate
no matter how they are arranged and connected, except for the
default output unit's output connection which is always 441000.
Have I analyzed this correctly?
