How can i Amplify mp3 Sound in Android programmatically

Question

I am using some mp3 files in my android aap. Its volume is very low. How can i amplify its sound by 3 times programmatically.

Can you do this with Equalizer? http://developer.android.com/reference/android/media/audiofx/Equalizer.html — Edwin Evans, May 31 '12 at 00:16

If you want to boost the mp3 sound programmatically then it will cost a lot cpu usage, (which for a low end device is a serious matter) and also you have some pre-loaded mp3 to play so my suggestion is to pre-increase the sound volume of those mp3s (using some sound editing software like audacity) and then use those in your app.

If you use SoundPool, the play function includes a volume parameter. Does that help? You should boost the sound in the file itself though as @orchidrudra suggests as this will only let you make it quieter.
