[Sursound] Technical Tour: Sydney Opera House

2019-01-14 Thread muhammad hafiz wan rosli 
Greetings,

My name is Hafiz, and I have been lurking around the group for some time.

I am currently in Sydney till the weekend, and was wondering if there is
anyone here that can (or knows anyone that can) give me a technical tour of
the Sydney Opera House, specifically regarding the acoustics of the hall?

Thanks!

Best,
Hafiz

Re: [Sursound] Publishing music in ambisonics

2019-01-14 Thread Jon Francombe - Audio Team 
Hi All,

I've been involved in the work being discussed around "media device 
orchestration" — using an ad hoc array of connected, synchronised devices to 
create an immersive spatial audio experience. It's something we've been looking 
at in the S3A: Future Spatial Audio project (http://www.s3a-spatialaudio.org/).

Unfortunately, the trial production we released ("The Vostok-K Incident") is 
offline at the moment — we're working to get it up and running again and I'll 
let you know when it is. But there's information about how it was made and our 
thinking behind it here: 
https://www.bbc.co.uk/rd/blog/2018-10-multi-speaker-immersive-audio-metadata.

And some papers here: http://bit.ly/MDOpublications.

Happy to chat further about this—please get in touch if you're interested.

Thanks,
Jon Francombe

I converted / rendered files in Reaper, In to  Opus, but a lot of other
media formats are available.

What file format do you have in the caf container?
