Very Poor Update This was, by far, the greatest app until this update. This version does not read the folders on my external SD card, and so it is now impossible to amplify a whole album of songs at once like it used to be in the older version. It is much much slower in loading even one song and in amplifying them, often causing the phone to lag. It is completely ruined. All in all, this app, for me, no longer works, and you've lost me. I still have the older version though in my other phone. It does NOT even work anymore.
Good idea, badly implemented You can change the gain on an MP3 by editing the frame headers for non-destructive volume control. This app actually decodes and re-encodes the MP3 which damages the audio data :(
Bad app It doesn't do what it says. Tried it on a 55 min audio file
Great You should attempt to make another version of this app, that instead amplifies MP4 files. If that's possible.
Junk Crash every time.
