Default [Q] Sound Enhancer without custom rom?

Hello,

I'm not new to the rooting and unlocking area but I am new to the Samsung S3. I've rooted a EVO 3D, HTC DNA, and a couple other phones and now I'm at this Samsung S3 (SCH-I535) Baseband I535VRUCML1 (after using ODIN because I had VRUCNC1). I've successfully rooted the phone using safer but I couldn't "safestrap" because my phone is encrypted.

Anyway. My question is I'm looking for an audio DSP or something like Beats Audio that will make all the audio on my phone enhanced without doing much (I don't know much about audio but I know these speakers aren't quite great). I did some research and I see a Beats Audio I could flash but I need a custom recovery. Well I can't add a custom recovery to my phone. I can get a program with enhancements while I play that I can adjust while the media plays but I'm looking for all audio whether it be from Pandora or my music player not just one source. My question is does such a think exist for a normal rooted phone without a custom recovery? It doesn't need to be a name brand it just needs to work.

Thanks,

Balask
