What are the computational requirements of immersive audio?
There are several ways to implement immersive audio, each with different computational and hardware needs. Calculation of the head-related transfer function (HRTF) is an important aspect of deploying immersive audio. This FAQ begins by detailing what an HRTF is, looks at an open-source program for calculating HRTF, and then considers how cameras and inertial measurement […]
What’s the difference between object- and channel-based audio?
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 […]
Filters limit EMI and audio distortion
TDK Corporation has announced the introduction of its compact MAF1005FR series of EMC components, measuring 1.0 mm (L) x 0.5 mm (W) x 0.5 mm (H). These multilayer chip components are designed to improve sound quality and reduce noise interference in the audio lines (sound lines) of smartphones and other devices such as tablets, wearables, […]
How does artificial intelligence relate to immersive audio?
Tools like neural networks (NNs), machine learning (ML), and artificial intelligence (AI) are being applied to hard problems related to immersive audio. This FAQ will examine how NNs and ML are being used to up-mix audio tracks into their original constituent parts, how NNs are being used to produce personalized head-related transfer functions (HRTFs) and […]
What is immersive audio and how does it work?
Immersive audio extends conventional surround sound technology into the third dimension. It adds height and more to the audio experience. This FAQ presents some of the basic concepts of immersive audio, looks at how ambisonics relates to immersive audio, and closes by looking at a new recommended immersive audio system design practice. Immersive sound transforms […]
