When I recorded Haley Jo's lovely voice for the original eight directions, I also recorded her announcing other directions. Unfortunately I wasn't prescient enough to record every conceivable direction. I wonder what would be a good announcement for half height positions? Sent from my iPhone

Don't forget the programs 'copysfx' and 'chxformat' in the CDP MultiChannel Toolkit enable users to tinker with channel masks, including setting to zero (if that helps), or of course to write a plain old multichannel WAVE file. Richard Dobson http://people.bath.ac.uk/masrwd/mctools.html

Hi Aaron, Currently the channel layout for upload to YouTube must be 4.0 or unspecified ; e.g., with ffmpeg, specify "-channel_layout 4.0". We're working on improving things regarding other channel layouts. Apologies for the confusion in

Is there some trick to uploading these files? The files I make upload, but then fail during processing. I make the files like this: $ /opt/local/bin/ffmpeg -loop 1 -framerate 30 -i cube-1920x960.png -i > AJH_eight-positions-ambix.wav -map 0:v -map 1:a -c:a pcm_s16le > -channel_layout quad

Re: [Sursound] YouTube now supports Ambisonics (warning....part advertisement..)

Hi Chris. Can you give us more infos about this "open source" object-based platform? Because sometimes, "open source" can mean "mostly closed". Also, PCM (or LCPM) is a lossless format; how can DSD sound better at the same resolution? Are you referring to the format or the hardware? -- Marc On

Re: [Sursound] YouTube now supports Ambisonics (warning....part advertisement..)

DTS-X is based upon an open object codec that SRS labs developed and open sourced,     the decoder  is a proprietary implementation but anyone can make their own decoder. DTS acquired SRS labs to get the technology, it is superior to Dolby Atmos and is scale-able from bin-aural headphones all

Re: [Sursound] YouTube now supports Ambisonics (warning....part advertisement..)

I could provide an online listening test to compare PCM and LC-AAC (compressed with the FDK-AAC encoder), with a live A-B switch, along with the graphs that Aaron made, so that people with scientifically enhanced golden ears can give some feedback. A blind test would be even better. With the

Hi David, if you are asking if the ACN/SN3D FOA is the same as the B-format, yes, first-order is the B-format anyway you look at it. The B-format in ACN/SN3D convention is the same as in the traditional definition without the W scaling and in the ACN order: B_ACN_SN3D = [sqrt(2)*W Y Z X].

Hello all, Some welcome news, YouTube is now supporting ACN/SN3D FOA attached to a .mov video container as uncompressed PCM audio. This is great, as most of the world gets a lot of their content through YouTube and now they'll all get to experience the power of Ambisonics!. For now, it only
