Sonic Studio III

Sonic Studio supports HRTF-based (head-related transfer function*) virtual surround for VR headsets, casting an immersive aural landscape that draws you deeper into the action. The intuitive Sonic Studio interface also offers a range of EQ options and one-click presets, allowing you to tailor acoustics to suit personal preferences or the characteristics of your headset.

SONIC STUDIO LINK

The new Sonic Studio Link allows you to apply Sonic Studio effects on all playback devices. Simply press the Sonic Studio Link button to enjoy the effect on any connected device.

SONIC STUDIO VIRTUAL MIXER

Mix your voice and video game audio together using this software specifically designed for streaming applications. A variety of settings and monitoring.

APP-SPECIFIC PROFILES

Apply customized 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 dts

ROG Strix B550 series motherboards are pre-loaded with the DTS® Sound Unbound™ app that envelops you in audio as never before, conjuring whole new levels of immersion for extraordinary gaming and entertainment experiences. By leveraging Windows Sonic spatial technology, DTS Sound Unbound delivers audio in a virtual 3D space — putting you right in the middle of the soundscape, where you can sense the location and direction of every gunshot, footstep or other sound in your virtual environment.

* 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 center, where sounds seem to travel in all directions.

All-round Performance

ROG Strix B550-A Gaming provides robust power delivery to fuel Ryzen’s cores, comprehensive cooling, and support for faster memory — so it has everything you need to load up your build with high-performance components for playing in the big leagues.
