i had not beene following this discussion but i have just purchased the zoom 
h2, and it records 4 channels using built in mics. and daniel courville has 
some apple software to convert the four channels into 5.1

Terence--

On your budget and with ease of operation,.. there is no recorder 
that I'm aware of. Those expensive recorders could be regarded as 
over-matched for the mics used in the HD3 too.

Perhaps you could borrow a 4 track recorder or rent one and conduct 
some experiments with it? I would think that one could extract <125 
Hz content from one of the L or R Front mics in post without serious 
quality loss and thus not have to record the "discrete LFE " channel. 
What mic is that on top, facing up? Is it full bandwidth?  So much of 
the sound content in natural locations like forests comes from 
overhead,.. I'd consider mounting a "center" speaker" overhead for 
playback and record the LF, RF, Up and LR+RR (phase cancelled) 
signals.  If the top mic is currently LFE, you could swap that 
capsule with the current, "center." Even if the full bandwidth "UP" 
mic is played on a normally placed center speaker it could produce a 
more interesting image than using the center mic.

These solutions may seem radical, but you might be surprised at how 
similar or acceptable the results from a 4 channel recording can 
sound. I assume there are ways to apply Ambisonics B-Format  plugins 
with your Holophone rig using 4 channels to generate 5.1 as well. Rob
