Many consider stock Android’s music management and sound output to be sub par. This manifests in developer efforts to fix the situation such as equalizer applications and the porting of Beats Audio to every Gingerbread ROM. Since Google is presumably not working on making audio more exciting, it is up to the developers to keep the audio enhancements coming. XDA Senior Member D3HuM4NiZ3D has also ported the Dolby Sound Enhancer to the Samsung Galaxy 3.
Installing Dolby Sound Enhancement will, first and foremost, delete anything even remotely related to Beats Audio on your device if you already have it on there. However, many users agree that Beats Audio delivers too much bass, and Dolby delivers better overall sound quality. Opinions aside, this mod has only been tested on CyanogenMod 7, and not on FroYo or ICS builds for the device. D3HuM4NiZ3D invites anyone to give it a try on the different OS builds but assumes no responsibility if something bad happens.
If this sounds like something you’d like on your Galaxy 3, check out the modification thread. Also, don’t forget to make a backup, especially if you plan on trying this on an unsupported version of Android.___________________
