This sound effect is a spatial effect.
Unlimited presets :
You can create and manage as many presets as you may want to.
Start on boot :
If an effect was activated as the phone was turned off, it will now be automatically set on phone boot.
Homescreen Widget (2x1) :
This widget allows you to (de)activate audio effects and to change their values. To set a preset, you directly have access to dialog with a list.
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 may launch the app as well. But this happens only once. The goal is to provide a quick way to change between profile without opening the app. These shortcuts are entirely customizable and you can even choose which audio effects or preset auto-detection options will be affected by the shortcut.
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, capitalization and blankspaces don't matter) and a "Hard Rock" preset to get finer equalizer settings for each genre.
This feature requires to use a compatible music player and to have the audio file locally stored and correctly tagged.
Preset on call/sms/conversation :
Bass Booster Pro will automatically switch to the preset of your choice if there's an incoming call or sms. This will work even if the equalizer is off. It could help you to boost the volume to avoid missed calls. You can choose to automatically set a different preset during a phone conversation as well.
There're 4 themes in the app to offer some customization option to users who would be bored by the default white and black theme.
Option for decimal dB :
This is a small option to show the decibels with decimal precision in the equalizer.
This audio effect is still in Beta-state and will maybe be removed in the future because it doesn't work on most phones anyway.
Hoping you'll enjoy it, here's the Google Play link ;)
