Hi Eric,
Well, if we are talking about laptop based systems, a lot of interfaces
(like my personal Edirol FA101) have eight analogue inputs plus two more on
an spdif input. Not, therefore, beyond the bounds of possibility to add an
external box to do analogue to SPDIF conversion to get to ten
channels....might need to record an all channel click on each recording to
ensure any interchannel delay differences can be cancelled out. Do I gather
from the fact that you are asking about numbers of channels that you are
doing A-B conversion in hardware not software??

I was, in fact, fishing for your opinions on the number of channels.
Personally, although I retain some sort of purist perspective that a
complete 9-channel 2nd-order system would be best, when bringing in the
difficulty of taking along that 9th channel on a recording expedition,
2nd-order horizontal or a mixed order representation becomes much more
attractive!
What I am building presently is designed to fit with my own recording
needs which include portability and being relatively inexpensive. For me,
an 8-channel audio interface attached to my laptop is reasonably
attractive, although something like the Tascam DR-680 (at 800 US $) is
more attractive. The DR-680 is certainly more expensive than two Zoom
H2s, although not a LOT more expensive. Real recorders always seem to be
better than a computer + interface when it comes down to practicality.
Beyond that, connectorization, powering, sensitivity to vibration and
wind are all issues that have to be dealt with. I'd like to be able to
put all the gear in one bag and go recording. Microphone, cable, stand,
recorder, and that's it. For me, many recording opportunities vanish
because of what I'll call opportunity cost. I need to be able to grab it
and go.
Comments? I'm quite interested in what any of you have to say.
Eric

i would be happy with eight channels. (can i synch two zoom H2s?) i think
ambisonics will only take off if there are cheap simple systems that many
people can use. at home now i am setting up an eight speaker system,
about 50 watts per channel, with a total cost including an eight channel
d/a of less than 400 USD. i only have to wire up the eighth loudspeaker
(why does inertia kick in right at end? i can understand at the start.
fear of failure?)

How many would you like for it to be?
Recording 9 channels for 2nd order is a little unattractive in a world
in which
audio interfaces typically come in groups of 8. But if one is willing
to consider recording only horizontal (5 channels) or mixed order with
2nd-order horizontal and 1st order vertical (6-channels), it becomes a
lot more tractable.
Both of those handily fit within the capabilities of the Tascam DR-680,
for instance.
There are other considerations. Although we might like to record
periphonically
for a future-proof recording, therre are some real difficulties
associated with
trying to reproduce 2nd order material with-height using a loudspeaker
array that fits in a normal domestic room.

dear eric
first question. how many recording channels will it need?
