Stereo micing question

[engramic]

Whenever I have used a pair of mics for stereo recording in studios, I have always observed the 3:1 ratio when using spaced pairs. However, I've never known why exactly having a distance of less than 3:1 between the mics from the sound source causes phase cancellation.

Anyway, I am unsure as to why binaural mics are rarely (I assume) given the same 3:1 consideration. Can someone give me a definitive answer?

Im about to buy some binaurals myself, for recording music lessons. Im considering Giant Squids or Core Sound LCSB.

Can't answer your 3.1 question, but possibly it's because binaurals face out to each side, like your ears, so that may affect the phasing.

Listen to the sound samples on the Giant Squid site, they sound tinny to me. Maybe they were using too much bass roll-off, but if not they just don't have a decent low end.

Core Sound should be better, and Sound Professionals is still selling its most basic binaurals on Ebay for $25, and they sound superb too.
