Hello, I'm new to this group (even if my colleague Jerome (Daniel) shares sometimes info about it) so I hope you will excuse my usage of this list for the following information and questions ... The MPEG audio group is about to start a standardization process in order to create a 3D audio codec. As 3D audio experts, you are welcome to assist freely to the MPEG-H 3D Audio Workshop in Stockholm on July the 18th (all details here: http://www.audioresearchlabs.com/mpeg-h-workshop/101-3D-AudioWorkshop.pdf)
very interesting event! unfortunately, i have heard about it only now, and won't be able to attend on such short notice, but please keep me posted about future events if possible.
> This codec should have the ability to flexibly render an audio
program to an arbitrary number of loudspeakers with arbitrary configurations. I think it could be a good opportunity to make it also support HOA format (as input of the audio encoder, output of the audio decoder, or both), and not only classical "multichannel" formats such as 5.1, 7.1, 10.2, 22.2... In this context, could you please send an email before July 11th to [email protected]<mailto:[email protected]> indicating in just several sentences: - if you support HOA format as an input of the future 3D audio encoder, and why (what use-cases?) - if you support HOA format as an output of the future 3D audio decoder, and why (what use-cases?)
i definitely support higher-order ambisonics as an internal data representation of a future 3D audio format, and also for input and output, because of its scalability and independence of loudspeaker layout.
- please indicate also what is your point of view: content creator, capturing or rendering device manufacturer, researcher, developer ...
besides my work as a sound designer, event engineer and audio consultant, i'm an independent researcher and recordist of HOA content. my arguments for the use of HOA can be found in some project reports i have published:
