Meh
I was dissapointed with this app for several reasons.
1) The description is a little decieving. While you CAN adjust many audio tracks at once, you can only do so by using their "auto-detect" function-which was faulty.
2) The in-line player is poor. No support for playback using spacebar and the play button is this tiny little button, which furthered my frustration with the fact that I had to manually adjust each track.
In the end, I got the app to do what I wanted, but I had to do it manually. The app is cheap, because it is cheap.
