I love DSP Manager, but it wasn't included Harmonia and that made me sad. So, with some quick google searching skills, I found out how to add it to Harmonia (or any other ICS Rom) I'm attaching the files you'll need. This is not a flashable ZIP; you will have to unzip and move things around using something like Root Browser. Instructions: Spoiler DSPManager.apk should be placed in system/app audio_effects.conf should be placed in system/etc (overwrite existing audio_effects.conf) libcyanogen-dsp.so should be placed in system/lib/soundfx You should remove the following .so files from system/lib/soundfx that are not required: - libaudiopreprocessing.so - libbeatsbass.so - libsrsfx.so Remember to set permissions to rw-r--r-- for each file you've changed. Reboot and enjoy DSP. Also, I'm not at fault if you brick your phone. This worked for me and should work for you, too. Confirmed working on my phone.
