AES Europe 2026

Streaming of immersive audio is known to western audiences
almost exclusively in the object-based format, Atmos,
developed by Dolby and employing lossy codecs to limit bit
rates. Other object-based formats like Sony 360 have had
limited success, and until recently there were no channel
based streamed versions. But this situation is changing,
as it has already done in Japan.

Responding to growing interest in very high quality
immersive music for both on-demand streaming and live
broadcast, two new services are now active that offer,
first, channel-based audio and second, audio streamed in
high res PCM. Binaural mixes, a range of PCM formats and
video are variously included, with extensions to portables,
loudspeakers, and home theater.

This workshop provides a forum for discussion of both the
genuine promise and the challenges in these new
initiatives. Included are the advantages of high
resolution over lossy; channel-based versus object-based;
the degree of adoption of transducers for multichannel;
adaptive bit rates; data sources; and the Japanese
approach; amongst others.
