Re: [Sursound] realtime 5.1 streaming over hdmi ?
My macmini 2012 does 8 channels of hdmi with no problems - either out of HDMI port or with a converter on the display port out. Ive used it for 5.1 7.1 and some ambi outputting without problems. The av box i have is a pioneer lx82 and has to be set correct - direct pcm - i think mine has to be set before the mac will even recognise it. My 2010 MBP will also do it and that has no thunderbolt on its display port which surprised me. Have it set up so that programs load and start on boot up or by timer and for backup - clone the whole drive to a usb drive that can be booted from if the mac has a dicky fit mick On 8 Mar 2018, at 12:53, Augustine Leudar <augustineleu...@gmail.com> wrote: > Any idea if a Mac min would do that too ? > > On Thursday, 8 March 2018, Felix Andriessens <fe...@andriessens.de> wrote: > >> >> This might depend on your PCs graphic card, too.

Re: [Sursound] Cellphone tetrahedral
Im about to finally investigate all the newcomers to ambisonics with VR/phone stuff but this site is very short on detail ie the mic might work with ios but are they doing the app it would need, can it be plugged straight into a computer - will it need an app there too? Id like to ask a simple question to this debate about SN3d/Ambix format files in order to check the pingpong file? I remember in the early days of ambix a simple explanation of the reordering of fuma wxyz to wyzx and adjusting the W level by sqrootof2 ? I know there are a few converters around but is this possible without a converter within a DAW - the routing change is easy but adjusting W by 1.414 - can that be done in reaper or protools? best mick ritchie On 18 Aug 2017, at 18:57, Wim wrote: > It's probably USB audio compliant.

Re: [Sursound] Muti-channel ambisonic audio in sync with video
I have used QT7 for 1st order wavs on loop and for 8 tk tk wavs for discrete playback without issue though you should check any decoder latency when using 16 channel - 4 did have have small latency but not a problem given the material involved. I use Soundflower and aggregate audio devices without problem but the new "Loopback" software avoids these but im not sure yet if it passes multis from QT Also with video playback matching the resolution of the file to your playback needs is most important followed by the codeq u choose. Qlab is a promedia player of choice for theatres these days and will handle multiple videos plus 24 track audio midi and osc. Its advantage over a simple QT type playback is the ability to adjust audio playback to compensate for encoding latency. You can test it for free though only in stereo - but you can rent it for a few dollars to get the full mullarky for testing mick On 9 Sep 2016, at 03:59, ByungJun Kwon wrote: > Thanks for the information. > Did you try high order ambisonic encoded audio in video file? > What was the number of audio channels that you tried in VLC( or other > players)? > > Best, byungjun > > > On 09/09/2016 10:17 AM, Marc Lavallée wrote: >> It's already possible to play a multichannel audio/video file using >> VLC (or other players) while decoding tou ambisonic; it's a matter of >> configuring the system to redirect the multichannel audio of the video >> player to an ambisonic decoder, using a sound server like Jack. >> -- >> Marc >> >> On Fri, 9 Sep 2016 09:57:07 +0900 >> ByungJun Kwon <byung...@gmail.com> wrote: >> >>> Thank you very much for all your feedback and I think it's enough >>> information to start with. >>> Though if I were a professional visual person, I would prefer to play >>> it from the dedicated media player like Quicktime or VLC rather than >>> the one which resides inside DAW.

Re: [Sursound] Muti-channel ambisonic audio in sync with video
Hi interesting xjadeo which ive never seen but if youre using reaper u could just use a version on each machine and use your audio machine to generate timecode and send to reaper on the video machine via network midi and have Reaper with only video on it - I understand Reaper5 is better for video but havent used it. In osx its all in the system but with windows machines youd have to set up some network midi software to recieve or and send. MidiYoke and LoopBe are in my memory but i dont which windows os they work with and you dont mention what youre using I use ql;ab for video things but its not cheap and only mac - but well worth it mick On 8 Sep 2016, at 07:52, ByungJun Kwon wrote: > Hello list, > I have an exhibition of playing heavy duty video file together with 16ch > interleaved ambisonic wave file.

Re: [Sursound] ultra-cheap m/c USB cards for the R-Pi?
After discussions here 18 months ago on these usb boxes I bought this same asonic ( though called something else) for a premium price then of £14 and it worked through osx 10.6 without a hiccup - I bought it for cheap playback tests of multiple audio outputs from bidule/reaper and it worked after setting up the outputs in OSX with no driver needed. On older macs it can hiccup using 8channel out but set it back to 6 channel and its fine - continual audio dropouts on all outputs - I never got to the bottom of this.

It even worked with Protools9 which was brand new when I got the box and is the most choosy of programs Sound quality I guess is similar or worse than standard inbuilt outputs - oh and the usb connection isnt deep enough meaning it falls out if you move it other than that it did what it says on the tin mick On 27 Jun 2012, at 08:01, Bo-Erik Sandholm wrote: Maybe you are looking for something like this £ 10,37 http://blog.rtwilson.com/review-asonic-external-usb-2-0-8-channel- sound-card/ -Original Message- From: sursound-boun...@music.vt.edu [mailto:sursound- boun...@music.vt.edu] On Behalf Of Dave Malham Sent: den 26 juni 2012 10:00 To: Surround Sound discussion group Subject: Re: [Sursound] ultra-cheap m/c USB cards for the R-Pi?

Re: [Sursound] online multichannel release: HTML5 test
Hi Etienne O This is similar problem Ive always had with SoundofSpace AAC files which use the CLRLsRsLFE order but again I can use the Quad playback to fix the order. Id much prefer the ITU spec of LRCLFELsRs as that seems to be a sort of common standard I understand that AC3 and AAC have different channel orders by definition. I'm pretty sure soundOfSpace does it correctly (for both). Are you talking about Firefox in OSX with a VLC plugin? ... or are you talking about Safari playing AAC natively? I hadnt spotted a firefox vlc plugin so am using browsers natively - and they seem to follow my general audio prefs - having said that and upgrading firefox to v8 now i cant play my own ref movies at all - eek but it acts the same as v3.5. Chrome I did try and it continually asks for plugins and shows me to too many google links for my liking. The first aac file order spec seems to be what soundofspace uses but I found much discussion online of using the more standard layout. AC3 has to be as is because external devices are all set the same It is ... I think what is needed is a table that identifies which 5.1 format for which browser for which OS for which stereo decode is best. Then I'll implement that (and others can implement that) and so people could say works with Chrome 10.1 + on windows, or etc. Etienne I'll have another look at the browsers as I need to get Firefox working again and try a windows machine as Ive got some tests to do for binaural mick -- next part -- An HTML attachment was scrubbed...

Re: [Sursound] online multichannel release: HTML5 test
Thanks for helps - I could see I was accessing the ogg version in my browsers and when I set my speaker config correctly I can get multichanel audio from the html5 page no problem. Well there is a problem and that is the file order - with a 5.1 config set in OSX im seeing a LCRLsRsLFE playback but im not able to save this as a config and to add to that Quicktime and VLC only play out tracks 12 and 5 - but I can change to quad playback and then all 4 tracks are routed correctly. This is similar problem Ive always had with SoundofSpace AAC files which use the CLRLsRsLFE order but again I can use the Quad playback to fix the order. Id much prefer the ITU spec of LRCLFELsRs as that seems to be a sort of common standard On the main site Ive never been able to get a player to load with the AC3 play now option though I can download them and play back dolby digital in VLC and quicktime through my Yamaha home decoder. Using VLC is easily the best because it has its own encoded stereo option which saves changing overall options and I can it triggers the yamaha recieving it. Quicktime does work though but only if you go into the terminal and set up ac3 passthrough?? hence I use VLC for AC3. AC3 in OSX appears to always download rather than just playthrough - it will open and play in VLC but only after downloading as well. My use of AC3's has been mainly dvds for film or straight audio for multispeaker installs ignoring 5.1 - there is an answer to the download issue as you can save a vlc playlist and post as an m3u containing the urls to avoid ac3 downloads though ive only just tried that out. So I dont see a particular browser problem though we are dealing with computer and receiver set ups - I originally wanted to be able to stream 4 channel files into soundflower without any need - for people to reset or guess channel order and with Ogg files the computer tended to mess with the order but when I used a QTreference file as the link the channel order was not messed with anymore - this was only tested in OSX and XP at the time hope this is of help to someone - mick On 1 Dec 2011, at 22:40, etienne deleflie wrote: Hi Mick, If you are talking about this page: http://soundofspace.com/static/test_html5.html then all feeds are 5.1 if you are hearing stereo it is your browser that has decided to interpret the 5.1 feed as stereo.

Go for the highest spec as they are a bit limp and I remember adding 2 channels of audio silence to ensure all players see the same thing - also some players like vlc need a good one second start before theyve communicated youre in dolby digital to the decoder and you can miss the first note. For streaming with bformat or 4 channel files I found ogg files to be the best quality and I also had grief with VLC - first they worked then after a week they crashed VLC over and over again - I just tried a couple of them and now VLC doesnt read them at all - something about XoX files not being good whatever that means. I just looked online for any developments and came across many problems including my 2008 request that went unanswered.

Re: [Sursound] online multichannel release: HTML5 test
Etienne - I can play back stereo from your player in firefox3 and Safari but not 5.1 - my 5.1 box doesnt see dolby digital just stereo. Is there any way of telling which feed my browser accesses? mick On 29 Nov 2011, at 23:51, etienne deleflie wrote: Hi Fabio, Worked fine with Safari and Mac OSX. I tried using jack. It immediately showed the 6 channel web process in the routing window! Also without jack it directly played back. Could you give some background on the HTML5 implementation or on how you realized this? its simple. One of HTML5's advantages is that it is the browser that supplies the media players. This means less need for 3rd party media players like Flash / Quicktime / VLC etc. That means less barriers to entry .. which means there is a growing chance that more people will 'just hear' 5.1 coming out of their connected speakers (if they have them connected to a 5.1 card). Here is what the HTML5 code looks like (audio is an HTML5 tag): audio controls=controls source src=someAACFile.m4atype=audio/mp4 / source src=someVorbisFile.ogg type=audio/ogg / source src=someAC3File.ac3type=audio/ac3 / Looks like your browser does not support HTML 5. Non HTML5 code would go here. Perhaps a quicktime plugin for the old browsers. /audio The browser chooses whichever one it can play, and supplies the media player. And that seems to be: IE9 + : AAC Safari: AAC Chrome: AAC / Vorbis Firefox 8+: none of them, but if you have VLC installed it will have a go at OGG and perhaps AC3 opened in VLC. It is Firefox that fails us here. Firefox can play Vorbis files, but not multichannel ones.

InternetExplorer 9 supports AAC, so does Safari and so does Chrome. So that covers around 50% of browsers. BUT ... it also covers the two main OSes. Firefox is the other 50% ... and that means Ogg ... not sure if firefox supports AC3 but I dont think it does. The only question is whether or not the Browser can successfully stream the 5.1 channels to the sound card connected to multiple speakers. ... any reports of success or failure would be appreciated.

Re: [Sursound] online multichannel release
Hi marinos i missed the bginning of the debate but I went down this road 3 years ago to stream bformat files For your requirements with 4 channels of discrete speaker files I think ac3 is by far the most accessible to anybody who has no 4 channel sound card - a digital link between computer and home ents system and you have 4 speaker playback without any tweaking. Go for the highest spec as they are a bit limp and I remember adding 2 channels of audio silence to ensure all players see the same thing - also some players like vlc need a good one second start before theyve communicated youre in dolby digital to the decoder and you can miss the first note. For streaming with bformat or 4 channel files I found ogg files to be the best quality and I also had grief with VLC - first they worked then after a week they crashed VLC over and over again - I just tried a couple of them and now VLC doesnt read them at all - something about XoX files not being good whatever that means. I just looked online for any developments and came across many problems including my 2008 request that went unanswered. What I did find though was that by making a QTmovie ref file to the ogg file I could then stream in QTPlayer and Itunes(which doesnt accept Ogg) that was what i used. The QTref file allows you to ensure the correct track allocation which ther Ogg alone wouldnt do. I didnt have time to test with all players and just recommended Quicktime which most PC users have Now I can stream a 4 channel FLAC up to a point but FLAC was my preference for download - this was fine in VLC and easily streamed through a bformat decoder.
