EQ App for Overall iPhone System
Does anyone know of a graphic equalizer app for the iPhone that controls the overall sound coming out of the sound-out (headphone) jack?
Everything I've seen in the App Store looks like it works directly with the iPod and iTunes on the phone. I listen mostly to Pandora and SiriusXM connected to a larger stereo system through the headphone jack. That system has the typical pre-set "Rock," "Classical," etc. EQ settings, however, I'd like to brighten up the treble before it even gets to the stereo system.
I did come across the external adapter, iWOW 3D, online, but I'd rather not spend $60 if I can get decent results with a couple-dollar app.
Thanks, in advance, for your help.
