Sorry people, I didn't mean to start up WW3 with my comments about 
the 'perfect recorder!

Methinks, there must be something to having the ability to hear with 
two ears - if one is lucky enough to have kept them both on.  

If you've got a big head, like mine, there is probably a lot of 
difference between what the right and left ear hears, especially in 
a pub!

I don't know if that difference is referred to as a phase 
difference, or some other kind of acoustic difference, but I would 
like to know how to describe it, and would be interested to hear -
oops - from someone who knows.  

I'm currently working on setting up a website so that I can post 
some of my backyard 'in the field' recordings.  I feel they are duds 
but given the conversation over the past few days, I can see that a 
bit of ambience is allowed.  

I'm having trouble setting up my URL - my ISP hit a brick wall this 
past week with overload, or spam, or virus, or something that went 
wrong.  The ISP people told me to wait 24 hours and try again.  (The 
didn't say: Take two aspirin and call me in the morning.)

I went to the Links section of the Group site this week and got to 
listen to Syd Curtis's Lyrebird symphony. Magic stuff.  I've even 
played the lute Lyrebird selection to a couple of patients during 
consultations!! This appeared to work better than aspirin!

That new mike pre-amp with the jam-in-easily-replacebable 9V battery 
sounds like a nice bit of gear.  Watching what has been talked about 
on this list, I guess the 'holy grail' is to go to field proof high-
bit solid state internally noiseless recording device , with the 
input transducer and output transducer being the only flaws in the 
system for 'perfect' reproduction?

Oh, no WW4...

Greg ;)

Went to work today...in Alice Springs, NT, Oztralia

PS: They tell me 'Dubya' is in Canberra, but there was nothing that 
the PMD222 and the AT-815b were able to pick from this distance.
