[MOD] Quasar AtmoX Ultimate Sound Mod [Official] [LP/MM/N]

Quasar-Atmox Banner

After lots of research, testing and using my porting knowledge, I have finally made an ultimate sound mod which is inter-compatible with most of the AudioFX like that of CyanogenMod, Oxygen OS etc.

I have included the best sound enhancement systems in one ultimate mod called Quasar AtmoX. I am very thankful to various XDA members who shared audio libs and files from Xperia, HTC, Lenovo and other devices. I am also thankful to the devs of different sound mods Dolby Atmos®, Viper Audio, Xperia™ Audio Enhancement, HTC Beats etc.

After lot of hard work, searching, testing and help from other Sound Mod devs, I made QuasarAtmoX™ – Xperia™ Viper Atmos® – the best in industry audio mod.

Disclaimer: I am not responsible for anything that may happen to your ears or phone speakers due to your carelessness or misuse of this sound mod.

Note: It is recommended to be careful while using xLoud™ at speaker mode (higher volumes for longer time may damage phone speakers). And while using head-phones be careful with Dolby’s Volume Leveler.
