Great idea but poorly executed thus far. Needs a batch conversion option along with greater stability. A Material Design user interface would increase popularity. Waiting on a proper update.
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! 👍
Hard to use, easy to ruin file Watch out, previewing will save changes. I never clicked Apply Gain, which it says is required to change the file, but just by trying to preview it ruined the original/only copy of the file. I set the option to limit gain such that the file won't clip, but it's all extremely loud static now.
Great for mowing Podcasts weren't loud enough for me to listen to with my ear protection headphones while mowing. MP3Gain boosts the volume nicely. There's some mild distortion, but that goes with the territory.
Need to improve You need to add an option to analyze, to know the mp3 volume before converting. On the internet each mp3 has a different volume and this app does not show the volume (dB). So there's no way all the mp3 have the same volume.
