Well, as a quick example, you
can't do anything like this with AHP/Fission.
Notice what's going on... we're previewing audio from iTunes (this is our LivePreview technology we've filed patents on), hearing what it sounds like compressed before it's ever recorded, then changing the compression on the fly (we could even change the compressor, from AAC to mp3 if we wanted to), adding a few effects on the fly, and then recording it at a very low quality.
Then we decide "Crap, those effects sound bad, and we really need it to sound better than the quality we recorded it at." So in the editor, we just turn off the effects we recorded with, and then boost up the quality. And there it is.
Granted, we changed this immediately after recording it, but you could come back 3 months later and do the same thing. Never have to re-record audio again!
Some other things you can do in WireTap Studio (that you cannot do with the Audio Hijack/Fission combo) that might interest you:
crop losslessly --
normalize in realtime --
play with the format/compressor on the fly --
losslessly delete audio --
losslessly silence audio -- and of course the
LivePreview feature is pretty cool.
And yes, there's more... just a taste.
