MP3 GAIN

★★★★★ Reasonably good app. Just have to learn what you can do with it and what you can't. Obviously you're not going to get the android version to match up to the PC version. On last check, PC's are about 100x larger and powerful. Let's just be gentle. These guys can get turned off like anybody else, and we do need him to stay at the table, because I've scoured the Internet and this seems to be a one-of-a-kind app in the way it actually handles files. It works on the same file. All the others create a separate file which then requires you to now replace the "old" file with the "new" one in all your playlists. Also it doesn't alter the original file which means you can always return the files to its original state ... again all without ever losing its placement in all your playlists.

★★★★★ This was the only app that could increase my music for a Samsung Galaxy S6 Edge. It didn't ruin my music, I even did a comparison between Play Music and MP3 Gain and it was definitely a HUGE difference. I recommend using +3 db. And ONLY CHANGE IT ONCE because it automatically saves the next time you change it with what you already have added. If you do change it again by accident then you'll have to delete the actual file. Also, if you click on the music file by accident and don't want to change the db then just use "0" as it already is and then click "Apply Gain" so it won't effect what you already have set. Enjoy! 👍

★★☆☆☆ Can't batch process. I have 800 songs and I'm not about to load each one

★★☆☆☆ Doesn't work. Tried +12 and -20db changes, no effect. The interface is terrible as well. What looks like a refresh button is apparently the apply gain button. The buttons don't have any text on them so you're stuck guessing. No guide or explanation of how to use the app, and the navigation is white letters on top of light gray. Idiot design. The app doesn't do what its namesake does and scan the files either. This app is probably a fake, so go on a pc and get the actual program. At least you know that works.
