Smart Gain for Android

This app works as advertised.

It INCREASES the gain of songs too low-but does not DECREASE the gain of songs too loud

Does what it's supposed to but there is very little feedback or documentation on what and how to do it. A batch feature where it levels all the songs automatically would be awesome, but you won't find that here.

I purchased this app because of my recorded lecture files which were really important to me. The problem was that the voice of professor was too quite (I could not catch all sentences) even with max of my speaker volume because I was sitting on behind of my class when it was recording. I just dragged my file into program and click auto detect several times until the +dB does not change. Then I could listen my lecture clearly enough :)

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.
