Just watched the WWDC 2021 Spatial audio video.
Of course you need to use iOS/iPadOS/tvOS APIs …like for everything else.
For the fall 2021 OS releases (so different from what Netflix is doing today), the video specifically states that you can have spatial audio in games (that seems to already be the case with the new Tetris Beat arcade app, so already working with current iOS/iPadOS), so you do not need to use AVPlayer (which I believe Infuse does not use).
There is a new APII AVSampleBufferAudioRenderer that, if I understand well, could be used by Infuse to produce spatial audio Apple Developer Documentation
Anyway, Infuse 7.2 is supposed to have improvements and features for the fall 2021 OS releases so we’ll see what happens.
I bet we will have spatial audio in Infuse in not too long
@james do not hesitate to confirm
