One of the greatest feature of the CyanogenMod is the app DSP Manager contained within. You can install this app on any ROM on any phone.
In words of the creators themselves:
Gives enhanced sound processing capabilities. A simple application called DSPManager is provided to adjust the new audio parameters such as bass boost, 5 band equalizer, virtual room effect for all system audio.
Instructions:
- Install as APK.
OR Else
- Copy the file to ‘System/App‘
- Set Permission as : rwx rxx rxx
Done!

muchas gracias resolviste mi problema funciona muy bien
works fine dude,thanks from lg optimus one:)
How to set permission for the app??
Use any app like titanium backup or root explorer
I Have installed this on my Samsung Galaxy player YP-G70 and all the audio enhancement features are functional except the “Dynamic Range Compression” feature, which is the main feature I need! I assume the device needs to be rooted and flashed before this feature would work?
Dose this require root permission?
