Hi Steve!
Sorry, this totally went under my radar. I'll check it out and will let you
have my feedback in a couple of days.
Cheers! Rob

As there has been no feedback, I'm wondering if perhaps the plug-in is not
useful, or if you were not able to download it, or not able to install it,
or just couldn't be bothered to reply. If it needs some changes to be useful
then I'm happy to modify it, but without some feedback I've no way of
knowing what, if anything, needs to be changed.
I'm guessing that the "Amplify Effect" work-around was sufficient for the
task and that a separate Analyze tool is unnecessary. If that's the case,
could someone let me know and I'll not bother uploading it to the wiki.

Is there any reason why you're not using the current version (2.0.5)?. As
far as I'm aware this should be ok on a mac.
