Hi--

Here's a blind comparison movie created from the results of a moving 
pink noise test that is hopefully very similar to what Dan suggested. 
The (3mb .zip) download link is at the bottom of the blog post here: 
http://tinyurl.com/2egg33s Play it with QuickTime or a 
QuickTime-compatible player on your computer.

There were no changes made to the recordings other than matching 
playback levels. The mics were placed 6' high and as close as I could 
get them to each other without interference. The 3 samples in each 
group are recordings of the exact same speaker pan.  I've temporally 
also uploaded a 16/24 bit .wav of just the soundtrack: 
http://tinyurl.com/2em2gqw (2mb .zip)  I'm about to see if I can 
determine which is which myself. Rob D.
