Homescreen Shortcut :
This feature allows you to create a 1x1 homescreen shortcut that'll change Bass Booster settings in one click without even opening the app ! (see screenshots)
The *first* time you use a shortcut, some Android versions launch the app as well.

Preset auto-detection :
This feature allows presets to be automatically adjusted according to the music that is being played. Let's say that you're listening to some Alternative Rock music, by default, Bass Booster will automatically choose the Rock preset, but if you create a custom "Rock" preset, yours will be selected.
But it goes even further, you could create an "Punk Rock" preset ("punkrock" works just as good) and a "Hard Rock" preset to get finer equalizer settings for each genre.
This feature require to use a compatible music player and to have the audio file locally stored and correctly tagged.

Players that support auto-detection :

Google Play Music
JetAudio Player (recommended)

If your player doesn't work, just drop us a mail and we'll see if support can be added.
If auto-detection doesn't work, try to enable Last.FM Scrobbling in the settings of your media player. (For Winamp and some others players, you have to install the Last.FM app)
