The Lenovo A7000 is the first phone in the world to pack in Dolby’s Atmos surround sound technology. The audio quality is loud, and the clarity of vocals is better than other phones in its category. The Dolby Atmos app allows finer control of certain settings, such as dialogue enhancement, volume leveller and offers preset modes for music, movies, games and voice content.
This is the Dolby Atmos sound effect ported from a Lenovo rom. This should work on all devices (starting from Android 4.3) since it is a software effect. It might conflict with other dolby effects you already installed. Flash the zip, it will edit (not overwrite) your audio_effects.conf.
Please backup your ROM via cwm/twrp if youn want flashing this file
