No need for warnings, I regard all list members as my mentors

I will look for options to make a larger MP3 file. I do not
have the trained ears that the list members have so I am looking for
what you hear. When I play the file as a wave file I hear a better
sound when compared to MP3. Sort of like listing to a cheap fiddle
compared to a Stradivarius, the harmonics are not there and part of
the sound is missing, losing the full rich tones.

Since the distance was so long I thought the cone of focus
would be larger and give me more stereo.

Would the out of focus separation add enough depth to the
file to make it sound fuller? During recording I can pan the dish
to find focus but after the recording I have a problem picking out
what may have been to the side or was just farther away and in
focus.

It was easer to design the mount. Are you suggesting
that all parabolas should be mono when not using a barrier?

Just trying to make the parabolic sound more like the
original location when I have more than one subject. I also have a
hearing deficit and the dish plus minidisk amplification makes up
for the loss.

This sounds interesting and I will study my Audition manual
to see if I can figure out what you are describing. I may be back
with more questions on this one.

I am considering a SASS mount for them, I have the mic's
connector made so I can easily remove them from the dish.

Reach is one of my goals but I also want a more natural
recording.
