I told about libs from ARMv7-based phones, as BeatsAudio.
That is simply not true, there are plenty of enhancement libs that do work and are compatible with the EQ's they come with, they replace DSP.
An example of that would be the SRS patch from Burstlams thread.
I'd advice you to stick around a while and check this forum out before you post things like this, this isn't xda.
SRS patch is different, and it rebuilds for your device.
