I got this idea from an app called XenoAmp. You can set different profiles (EQ settings) that will be triggered based on different phone states. For example, if the phone is docked in a car dock, the "car" profile will be automatically applied. Personally, I would like to change the EQ whenever I connect my phone to my bluetooth stereo in my car. Is this something that's possible/in the scope of this app?
