John,
I have to agree with Greg, your MS processing did not work for me
either, when listening through headphones.
In the first clip the environmental noise is evenly spaced around me
and I can travel outwards, but in the processed clip I feel like I am
in a pressure cooker and can't escape.
Not a very technical explanation I know :-)
To save on all this post-production, the best quick solution for good
stereo from a pocket recorder is to use external head-worn electrets
(e.g. EM172s), quick to put on if they are mounted on a lightweight
headband from an old set of headphones.
