About this app

So you already set the volume to maximum, bought those cool headphones, but volume on your music or ringtone is still not loud enough?

♫ The solution might be as easy as amplifying those MP3s in question.

This simple application does just that in 3 easy steps:

1. Start it up, select the files that are not loud enough
2. Set the amplification factor
3. Amplify!


This app can boost the volume of your music or other MP3 files up to eight times louder!

This MP3 booster WILL NOT CHANGE YOUR ORIGINAL FILES! It will create amplified versions of them in the Music folder on your SD card (or external storage).

♫ You don't need to learn to use expensive and complicated audio applications, this simple app can take care of all your volume increasing needs.

♫ Also very useful for audio books where the talking can sometimes be almost whisper-like. Amplify those files, and don't miss anything while driving or working out.

♫ Use your phone to its full potential, make those speakers blast that ringtone super loud! The real limitation now is the physical capabilities of those speakers and headphones.

☛ Warning: too much amplification can cause distortion! Use the built-in preview function to test the result before actually doing the conversion.

You can even choose to use the resulting files as your phone's ringtone!

☛ NOTE: since phone processors are weaker than desktop or laptop processors, amplifying a file sometimes can take significantly longer than on a real computer. This is the limitation of the hardware, as MP3 Amplifier already uses fully optimized MP3 processing implemented in native code.

Ratings and reviews

I have had this app for years, its been my go to for sound amplification, but unfortunately sometimes when I amplify a song its gets kinda extended? Like my music player shows it usually gets an extra 20 seconds to 2 minutes from the original file, now these parts don't play it just skips after it finishes, but its hard to seek and those files tend to get corrupted after awhile, if this issue could be fixed I be more than willing to give it five stars!

Does what it says! 1. Pick the songs to change; tap DONE; they appear as a list. 2. If you want to boost more or less than the default "1.5" (meaning 150%, it should prob. say that), tap & hold it, and a box appears, which optionally applies that boost to ALL chosen songs. ¶ If you need more features (preview etc), best use a full audio editor. Giving only 4 ⭐, as it keeps running in the background & using power (my phone warned me) unless you manually "kill" it—the author should fix that. 😉

to those who say you can only amplify it by 50%, then try to double tap on the music that you want to amplify and there you will get the option to amplify from 0.5 to 9.9.. it work great on me, definitely the audio volume has change, and the app doesn't crash.. ads? just turn of mobile data or wifi for a while when using the app.. its not that hard
