Simple, small, experimental free app to boost your speaker or headphone sound volume. Useful for movies, audio books and music.
USE AT YOUR OWN RISK. Playing audio at high volumes, especially for a prolonged amount of time, can destroy speakers and/or damage hearing. Some users HAVE reported destroyed speakers and earphones. IF YOU HEAR DISTORTED AUDIO, LOWER THE VOLUME (but it may be too late).
By installing this application you agree that you will not hold its developer responsible for any damage to hardware or hearing, and you are using it AT YOUR OWN RISK. Consider this to be EXPERIMENTAL software.
NOTE 1: This is NOT for adjusting the speakerphone volume in phone calls (that has its own boost, I think), but for adjusting the volume of music, movies and apps.
NOTE 2: Users who complain that this does not boost bass are right. In order to mitigate (but not remove!) the danger of damage to small speakers, there is no boost in the lowest frequency range, and there is also less boost in the highest frequency range. If you go to the Settings and uncheck "Non-uniform boost", you get an across-the-board boost, but that's much more dangerous to your speakers.
