Marc,
I think your assumptions are correct. We only set
kAudioUnitProperty_Latency for our plug that adds a delay to the input
- everything works as expected (hosts compensate for the delay
properly). I think kAudioUnitProperty_TailTime would be used in the
case of a reverb or some such that does not in fact delay the audio but
does add length to it.
I think if an effect has a delay and a tail these values are specified
and treated as completely independent (one need not be considered to
determine the other).

Does a value for the kAudioUnitProperty_Latency property imply that, at
the end of the input signal, there will still be output for an equal
amount of time? Or is an Audio Unit expected to return that same value
for the kAudioUnitProperty_TailTime property in such a case? To me,
latency means latency all the way through: it starts late and it ends
late. And then if there is an additional tail on top of the already
expected delay (from the latency), then that additional value would be
returned from the kAudioUnitProperty_TailTime property.
Are my assumptions correct, or should AUs add the Latency into the
TailSize?
Thanks,
Marc
