Hi Gus,
of course you can do what you suggest, but, speaking practically,
ambisonic recording, encoding and decoding makes it possible to,
for instance, go out into the field with one microphone, and record in
(only) four channels. Later, depending on the situation, I can decide
whether to listen in stereo, quad, with six or eight speakers or
whatever
I like if I use the particular decoding process. And it sounds great.
Another thing, some of the decoding strategies are neither elaborate or
expensive. I have a simple 4 channel ambi decoder programmed into the
built- in mixer of my computer's sound card. I just choose the
preset, play
the 4 channel B-format file and it decodes it for me. There are also
plenty of free or shareware vst and au plug ins to do the same thing.
It's really not all that difficult if you ignore all the maths talk.
Those guys on
the list are doing that so that the rest of us don't need to ;-)
(thanks guys)
best wishes, Justin.

Subject: [Sursound] Why do you need to decode ambisonic/b format
signals ?
Im sure Im missing something obvious here but humour me. With a stereo
signal I can just place two speakers in a line and have my stereo
signal
send two discrete channels to each speakers, each channel
representiong one
channel of my stereo microphone. The same with quadrophonic (with no
matrixing nonsense) - four mics go to four speakers placed in a
square -
works fine, tried it hundreds of times, no decfoding involved. Why
cant you
do the same for 3 dimensianal sounds ? Four mics surround sending
discrete
channels to four spekers placed in a square and one for height
information
going to a mic above your head - this should naturally represent
the sound
field without any decoding , Ive done this and it has been quite
effective
- so why the need for elaborate and expensive decoding ?
cheers,
Gus
