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. Ive not used dolby decodes on it but it also works for palyback with XP and Linux when tested originally. 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?

True - but but it looks like there's nothing precluding proper multichannel support except (!) the current defaults for output. Unfortunately the documentation is not too clear on this point (http://wiki.videolan.org/Documentation:Play_HowTo/Basic_Use/Audio#Audio_Channels) P.S.: Why can't all these university departments not simply < manage > to develop some own open source Ambisonics player, including the < Play > button?

[Sursound] Quicktime player ??
Hi, Date: Thu, 28 Jun 2012 06:05:49 +0100 From: Dave Malham Subject: Re: [Sursound] VLC Ambisonic player module Hi there, Whilst MPlayer is an excellent piece of kit, it's not exactly suited to people with little or no computer literacy, so someone on a Windoze machine and an audio file to play can't just be told to instal MPlayer - for them, mplayer -ao jack -channels 7 myvideo.avi is slightly less intelligible than the average inscription in a Pharaoh's tomb :-) Why was I asking about this? After all, I just run up Bidule (or Reaper, or Max/MSP) to do the job. Well, I was prompted to ask because a mate had just been packaging up some ST450 recordings as UHJ for distribution to the people he'd recorded and wondered if there was a way he could point them at whereby they could (easily) play them properly (ie decoded) via the Quicktime player. I naturally thought of something more openof course, Bruce did some stuff for the Windows Media Player, but it's not the same. I've never got round to trying this myself, but it seems as though Quicktime player, along with a few other bits, might be persuaded to do the job. You can get it to output multi-channel streams, which could be B-Format, or just use UHJ as suggested. Use Soundflower to send the audio stream to another application (e.g. Bidule, Max, Audio Mulch, Reaper), and find or build a decoder that works in it. Bruce's plug-ins are a good bet for this. Not exactly for the computer phobic, and you still need a fair amount of gear: multi-channel audio interface etc. You might be able to use HDMI if your computer can send LPCM audio streams via it to an AV receiver, and persuade said receiver to handle it correctly. Done once it should be possible to help others do it. Ciao, Dave Hunt ___ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound
