Dolby Access Premium ((better)) -

While the free version allows you to experience Atmos for Headphones via a 30-day trial, Dolby Access Premium (purchasing the license) removes the time limit, granting you lifetime access to spatial audio for gaming, movies, and music. It transforms standard stereo audio into a multi-dimensional soundscape, allowing you to hear enemies sneak up behind you or experience the full verticality of a film soundtrack.
