Bummer.... and SWEET Mini btw....Not aware of any RTA software for Mac. I'm currently running TrueRTA in Boot Camp, and it sucks. I will likely write my own barebones RTA with LabVIEW student Mac edition. I'm sort of a LabVIEW guru so it wont take more than a weekend. I don't think the student license allows for distribution, however
I also have this downloaded. I don't have a fancy microphone to use with it, but if you set its input to the built-in microphone on your Mac [a 24" iMac for me], it's surprisingly sensitive and will show you the RTA curve for a quiet room. After that, it has all kinds of measurements I haven't fully explored yet, owing to the lack of microphone and portability
So I spent about 2 hours programming an RTA in Labview, and it's looking promising I need to add mic calibration, weighting, octave bands, and dBu scaling, but the rest is done I've got it hooked to my Behringer ECM8000 and it's working pretty awesomely.
The best part is, it runs on my Mac; it doesn't crash; and I can @$%@! with it when needed. Future upgrading for impulse, waterfall, and test tone generation should be relatively straight-forward. This is DIY mobile Audio, I sometimes get carried away with the DIY part.
1khz test tone:
$800.00 and I don't even get a copy of the software on DVD? >:O
looks like it can't be used in OSX Lion. unless it still works? I know power pc support was taken out of Lion.
