Immersive audio uses various channel- and object-based techniques to deliver a high-quality listening experience. There are three general categories of spatial audio: channel-based audio (CBA), object-based audio (OBA), and scene-based audio (SBA) — that’s the next generation of OBA. CBA is the simplest form of spatial audio, but it’s not immersive. The basic form of […]

What codecs are there for immersive and 3D audio?
Immersive audio is a three-dimensional (3D) sound field created by combining lateral and overhead speakers. A variety of industry standard and custom codecs are available for implementing immersive audio. This FAQ reviews the operation of the MPEG-H Audio (universal immersive audio coding) codec and the still-under-development MPEG-I Immersive Audio (compressed representation for virtual and augmented […]
Half-bridge HEMT GaN devices simplify power-supply designs
STMicroelectronics’ MasterGaN1L and MasterGaN4L introduce the next generation of integrated gallium-nitride (GaN) bridge devices that simplify power-supply design leveraging wide-bandgap technology to achieve the latest ecodesign targets. ST’s MasterGaN family combines 650V GaN high electron-mobility transistors (HEMT) with optimized gate drivers, system protection, and an integrated bootstrap diode that helps power the device at startup. Integrating these features saves […]
