I am wondering if anybody has developed an app that can be used to add equalizer like qualities to callers voices. I have a Droid Bionic. I bought a Motorola Command One Bluetooth and when I would receive calls from ladies with high pitched voices it was painful. Sometimes, even without the bluetooth I wish I could add a bit of "base" to a female's voice. I bought a Motorola Sliver Bluetooth which has more base, but it would be still nice to be able to equalize incoming voices a bit. If I lower the volume it becomes difficult to hear such callers. It would be nice to have and equalizer and volume adjustment that would set for individual callers base on their caller I.D. (like the unique ringtone that you can assign to callers).
