The site was only 50 meters from the Long Island Sound
and even though the wind was minimal there was a low
surf running. Out on the beach the low frequency
environmental sound was overwhelming even the call of
the gulls. The recording site is shown on the lower
photo on my web page. The only filtering I did was to
run the output of the MD through a graphic equalizer
with frequencies below 250 Hz set to -12db. I am still
experimenting with the settings for recording level on
the MD. For this recording I set the meter half way
between the -12db mark and 0db.
The setting on the output volume of the MD when
transferring the audio signal also seems to be quite
critical. Sony suggests setting it to max but this
always introduces distortion so I back it off to about
50%.
I am unsure how to separate environmental and self
noise. A totally quiet environment is hard to find.
Possibly a flat plaine with no trees or grass on a day
with no wind.
I don't expect too much for $30.
