HATE audacity.... it is severly limited due to its open source roots... does not support ASIO directly...

but it does support VST's now i hear.....

cool edit pro is much better... although alot older... they were actually bought by adobe... and it is now called adobe audition... although it hasn't been updated in a few years now....

if i were you i'd get reaper http://reaper.fm its free to try will work forever... no protection etc... but its only 40$ for a license when you realize that its worth far more than that... you pay

the way that you would use autotune would be to sing in your normal tone whatever that is

and then add the plugin to the track... and it does the magic POST. you can monitor it while recording... but its very distracting with even the slightest latency.

you don't really bring any of into pod farm... thats just sort of a jam portal.....

you actually bring pod farm into your recording software... as a plugin....

you can open pod farm, arm your track.... record the DRY track....(disable monitoring in your recording software, only monitor pod farm) after you are done performing... add the pod farm plugin to the dry track... hit play... adjust to taste... as many times as you like without re-performing.
