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.

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!

Outstanding Job. This App Does What it Says it'll do. It Amplifies your music (files) not the music itself. It makes your Songs Really Come Alive. Hard to believe an amplification of only 1.5 x can make that much difference. My Heavy Metal Faves are definitely much Louder than they were. Works for me, This App is a Keeper.You Developers deserve a pat on the back. A handshake and praise for your work. WELLDONE!! Thankyou All Very Much.dk.Sam.s7act.

First of all, thank you for not pestering me with repeated requests to rate this app. Made me want to rate it more and more highly. App does exactly what it says, no more no less. Could be improved by allowing amped song to remain in view and played in case further amplification is needed or dissatisfied with initial results. But, if such changes would increase app size or degrade quality, please ignore suggestion. Thanks for a great little app that actually does what it's supposed to for free,
