Many users who have run a custom ROM before, or have been around XDA long enough, have heard of DSP Manager. It’s one of the most popular applications to include with custom ROMs, and it gives users the ability to tweak the sounds coming out of their phones to meet their needs and desires.
Prominently featured in pretty much all CyanogenMod ROMs and a number of other builds, it’s definitely among the top choices for system-level equalizers. Now, Samsung Nexus S users can now experience it on any ROM. XDA Senior Member devgee, with some help from others, has extracted the application from CM9 and posted it for users to install, regardless of what ROM their running.
The application comes with two methods of installation. The first is a recovery flashable update.zip. Devgee also provides the individual .APK so users can adb push the app directly to their devices. In a later post, XDA Senior Member snandlal shared the libraries necessary to get the application working. While these files were originally intended for the Nexus S, you should be able to adb push the .APK and required libraries on a variety of other rooted devices as well.
If you’re looking to get DSP Manager on your device, simply head on over to the original thread for download links, instructions and thread discussion. Don’t forget to make a backup first in case something goes wrong so you can restore!
