Xperia's sound has tuned in collaboration with Sony Pictures Entertainment and Sony Music Entertainment.
What is the difference between both tuning? and What is the user's benefit?
SPE (Sony® Pictures Entertainment) tuning is available for Dolby Atmos®. You can enjoy a multi-dimensional surround sound experience with the tuning.
SME (Sony Music Entertainment) tuning works for all sounds. The tuning faithfully reproduces the audio quality as artists intended, such as the localization of the sound of vocals and instruments.
