Issue related to 3D audio from MPEG-H #79

Closed LifeIsStrange closed 4 years ago

LifeIsStrange commented 4 years ago

MPEG-H is working on a new audio codec (mostly about improving 3d audio support) https://en.m.wikipedia.org/wiki/MPEG-H_3D_Audio I don't know if MPEG is working on another audio codec in parallel.

The issue has of course nothing to do with DASHSchema but I can't find where to contact the engineers that work on audio codecs at MPEG. I see that you have repositories for collecting issues relative to a codec such as

Official MPEG repository to discuss issues on MIAF MPEG-H 3D audio probably needs one too!

Anyway, here's what's my issue is about: I believe that researchers have made a breakthrough discovery that could allow to evolve audio codecs (and possibly h266 too but I'm not sure) I am talking about this: Experiment using Fast inverse chip z-transform

I'm not an expert, but this seems like a major discovery in signal processing!

From the comments I read: Sounds like a pretty awesome milestone to me. So, perhaps in the near future, new compression schemes might allow for reduced mp3 and mp4 file sizes, which means that for the same bandwidth we could see increased resolution/ higher frame rates

And

It should be a O(n log n) rather than O(n^2), so the speed increase for large n, which can be common n signal processing, is real.

Inappropriate content.

LifeIsStrange commented 4 years ago

@mikedo true but as an MPEG member you could still redirect me to the correct place. It seems that the correct place (a MPEG-H 3D audio repository) does not exist. With such a policy you will loose a lot of external contributions which is a sad and mediocre loss.

Turn up to ISO SC29 meetings and make a proposal.

LifeIsStrange commented 4 years ago

@paulhiggs you mean like meeting them IRL in Switzerland https://www.itscj.ipsj.or.jp/sc29/29w32901.htm ? ^^ that would be fun but I have not the motivation and I live too far away. Isn't there simply an email address or a slack channel?

I found it!! mpeg-h-techsupport@dmt.fraunhofer.org From https://www.mpegh.com/en/home/ Thanks, the issue is resolved
