Walt,
Thank you for your detail instructions on how to modified the SASS.
Your intructions have really helped me in getting my ideas
together.
After going through your sample recordings, I noticed that there was
a big difference in the background sound coming from the MKH and the
AT3032. The MKH had a more realistic sound, and the background was
much quieter. I apologize for this crude describtion and not
knowing enough about sound engineering to explain myself any
better.
