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 open....of 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
