I'd like to urge anyone thinking about web streaming formats to also consider how such a format could be used within the existing RSS-based podcast delivery infrastructure.
If there were an open format that had a reasonably good balance of file size/channel number/spatial resolution, and one could deliver that format via podcast RSS, it would open up all sorts of creativity for audio storytellers, documentarians, radio drama, and other more "cinematic" audio programs. Obviously this would require podcast apps/players that could decode HOA or other spatial formats into either binaural or channel-based playback systems--and I don't know of any that do at the moment. But this all seems technically doable. (Please get in contact with me if you happen to be involved in anything like this!) - Brendan -- Brendan P.
