Summary

In this episode of the Immersive Audio Podcast, Oliver Kadel and Monica Bolles are joined by the immersive audio workflow engineer Ceri Thomas from LA, US. Ceri shares his personal and professional journey that led him to working with Dolby and Apple at a pivotal moment when spatial audio began to enter the mainstream. He also discusses his latest consultancy venture, IMMERSV. This week’s hot topic was about the critical balance between quality and mass adoption of immersive audio in music.

Ceri Thomas is a leader in immersive audio and workflow innovation whose career spans film, VR, music, and product development. Beginning in London during a period of rapid change in post-production, he enabled creative teams to work without technical barriers as the industry transitioned from tape to disk, RADAR to Pro Tools, and analogue to audio-over-IP.

At Soundelux, Danetracks, and Todd-AO, he was deeply involved in the early rollout of theatrical Dolby Atmos, exploring its potential and limitations. He later joined Wylie Stateman’s Twenty Four Seven Sound, creating collaborative technical infrastructure and building an “Immersive Lab” for early-stage Atmos editorial, which led to Dolby recruiting him for its VR audio initiative.

At Dolby, he worked to make VR audio tools more accessible and then spearheaded the global adoption of Dolby Atmos for music, establishing delivery standards, room design guidelines, and integrating Atmos into top studios worldwide. His collaborations include projects with Manny Marroquin, Josh Gudwin, John McBride, Ann Mincieli, and George Massenburg.

In 2022, Ceri joined Apple Music as Spatial Audio Technology Lead, where he built the Spatial Audio QC process, redefined listening room and studio configurations, produced documentation for creation and broadcast workflows, and advised on immersive audio specifications internationally. In 2025, he founded IMMERSV, an independent consultancy working with consumer electronics manufacturers, DSPs, and broadcasters to deliver studio design, product development input, and workflow solutions for immersive audio.

Episode 120 Angela McArthur (UCL)

By Immersive Audio Podcast

Announcement

We’ve just submitted our panel proposal for SXSW 2026: “Audible Dimensions: Expanding Story Through Spatial Audio” We’ll explore how spatial audio is more than a technical enhancement but a powerful storytelling tool. From shaping emotion and perspective to guiding audience engagement, we’ll discuss how designing for immersive media means writing for space as well as time. As platforms like Meta, Apple Vision Pro, and Android XR raise audience expectations, spatial audio is becoming indispensable to immersive storytelling.

Please cast your vote and support our session here.

Thank you!

Summary

In this episode of the Immersive Audio Podcast, Oliver Kadel and Monica Bolles are joined by composer and sound artist Mariam Gviniashvili from Oslo, Norway.

Mariam works as a composer and sound artist – combining electronics, electroacoustics and 3D sound technology with visuals, dance and live performance to penetrate deep into the physical and emotional essence of sound and space. Growing up in eastern Georgia, she sang and played the piano, and studied composition in Tbilisi, Budapest and Oslo. Through her subject matter, her compositions display a curiosity about the world and society – from distractions during online meetings in DAYDREAMING (2022), to the viral patterns in DECONSTRUCTION (2020). Other works explore the Syrian war, a globally- sourced collection of songs and prayers, and a river soundscape in Oslo. Gviniashvili’s music has appeared at festivals all over the world – the New York Electroacoustic Music Festival (USA), BEAST FEaST (UK), Transitions at CCRMA (USA), ICMC (Korea), Mixtur Festival (Spain), ARD Hoerspieltage (Germany), Ars Electronica (Austria), Klingt Gut (Germany), Heroines of Sound (Germany) and Ultima Festival (Norway).

Mariam talks about her journey as a conventional composer evolving into a multidisciplinary sound artist performing her work in spatial audio on multi-channel arrays in different immersive spaces across the world.
