Couldn't be more clear.
guys, just get audiohijack.
........
it captures amazing sound quality from any specific app on your mac or any input
Audio Hijack is the best app for that, I don't know why Ambrosia launch something like that when it can work on something more powerful for Mac users...
One thing that a lot of people seem to be missing is the "come back later and work with a lossless source" feature.
For instance, if you set Audio Hijack to record into MP3 format at 128 sampling, that's as good as your audio will ever get without re-recording the source... You can certainly downgrade any audio as a copy which will come out sounding a lot like an original recording set at the downgraded settings, but even if you were to convert to 192 AAC, or even a lossless, it will still only sound as good as your original 128 MP3 (or whatever you first record at)...
With this app, if you decide you want to change the quality of your audio, you go back to your original and re-save (export) with your new settings and you'll get those "true" new settings.
This is fantastic. Especially for those "only one shot at recording" situations that come by some of us from time to time.
Granted, if you're dealing with many, many tracks of audio you'll need some HD room (to store all those lossless sources in the background), but hard drives are getting pretty cheap nowadays.
Nice job, guys. I look forward to it.
