This is from an interview at audiomidi.com:
----------------------------------------------------------------------
DE: You just released the AU versions of the Spectral plug-ins - was
there anything that you did or did not like about this new format?
TE: The nice thing about AU is that it is fairly well defined how the
host is going to interact with the plug-in. The other thing is that
channel configuration in AU is very flexible. If you want to make a
plug-in that is mono and suddenly expand it to eight channels it is
fairly easy to implement. The other nice things are more technical in
nature, like the fact that the GUI in AU is separated from the
plug-in. They have to communicate with each other through a little
protocol, which might seem awkward but because they are separate it is
more crash proof and the GUI can have its own performance
optimization.
DE: Does that separation have any effect on CPU load of a plug-in?
TE: Actually, I compiled my VST and AU and it is a very different code
base but the DSP stuff is fairly similar, the graphics are a bit
different, and the performance is within half a percent
- so they are very similar in that respect. It seems to
be more of a question of how well the host handles them.
