Re: iRig pre

Greetings,

I'm intrigued by the iRig Pre. For my field biology class I bought a $30 Ed=
utige EIM-001 i-Microphone for my iPhone, and it definitely made sounds som=
ewhat louder, which helped for our main purposes of recording unknown anima=
ls for later identification. The Edutige also worked with most of my studen=
ts' various Android phones, though it's not marketed as such. Any chance th=
at the iRig likewise has unadvertised Android compatibility?

My main question, however, is what microphone would be a good, inexpensive =
choice to connect to an iphone/iRig setup. My objectives, for now, are not =
to produce "publication quality" sounds, but to capture good-quality sounds=
 of birds, singing insects, frogs and toads for documentation and identific=
ation purposes. Portability is important, as I also lug around a fair bit o=
f camera equipment. I've looked at the specs of many different mikes, but a=
fter a while my head starts spinning as I don't know nearly enough to decid=
e which pros and cons are most relevant!

Cheers,

Alan
