I have been working at Norwegian broadcaster NRK in Oslo setting up a demonstration of "Next Generation Audio" with Fraunhofer IIS. The football from Russia was used as source material and MPEG-H content was streamed over DASH. The viewer could pick which language of commentary they heard, including the radio commentary for those wanting a more comprehensive description of the game. Viewers could also adjust the balance between the commentary and the stadium sound using simple presets or more sophisticated sliders. Sound was played from an immersive soundbar capable of playing content coded as 7.1 + 4 height speakers.
