APP-SPECIFIC PROFILES

Apply customised audio settings to various applications so that each is perfectly tuned to the way you want to listen.

*A head-related transfer function is an audio algorithm derived from sound data recorded through a dummy head. Test tones are played from a spherical grid around the dummy head to obtain subtle changes in sounds that come from different directions. The results are combined into an algorithm that allows Sonic Studio's virtual surround to process audio that’s true to life.

*DTS Sound Unbound requires in-game support. Check with developers for supported titles.

STEREO SOUND - Discrete left and right audio channels enable headphone or two-speaker setup.

SURROUND SOUND - Audio is split and served over multiple speaker channels – e.g., 5.1 or 7.1 – to create an enveloping experience on a single, logical plane.

SPATIAL SOUND - A virtual audio ‘sphere’ effect creates astonishing 360° immersion — with you at the centre, where sounds seem to travel in all directions.
