#1522: A Survey of Spatial Audio Formats with 1618 Digital’s Oliver Kadel

Oliver Kadel's 1618 Digital specializes in spatial audio sound design and engineering across linear immersive storytelling and interactive immersive experiences. Kadel also co-hosts The Immersive Audio Podcast with Monica Bolles, and I was recently featured in episode #109. I sat down with Kadel to get a survey of some of the spatial audio formats and production pipelines ranging from 3rd order ambisonics, object-oriented audio in game engines, working with the audio formats for Apple Immersive Video, Dolby Atmos, MPEG-H Audio, and emerging open standards like the Immersive Audio Model & Format (IAMF), which is "an audio container specification designed to revolutionize immersive audio experiences across a wide range of applications, including streaming, gaming, augmented reality (AR), virtual reality (VR), and traditional broadcasting." We talk about some of his favorite immersive audio productions, his process of getting a Ph.D. studying the impact of spatial audio on cognitive load, and some of the future trends of spatial audio.
