to do some recording.

an average of -20dB,based on an article I read, but I didn't set the low c=

Depends on what the soundscape you were recording was like, but you may hav=
e turned up the gain a bit high if a relatively quiet background was brough=
t up to -20.
Digital recording has such a wide dynamic range that a fixed level can be f=
ine for almost all nature recording. Speak in a conversational tone of voic=
e to your recorder at arm=92s length, and set the record level to peak arou=
nd -12 dB. That could give you a universal record level setting.
That said, the recorded noise level compared to the environment is mostly i=
ndependent of the recording gain. It is determined by the self-noise of the=
microphones. The mics on most hand-held recorders are pretty noisy. Fine f=
or recording urban soundscapes or popular music rehearsals. Too noisy for q=
uiet nature scenes.
Tascam doesn=92t publish a self-noise or S/N rating for the mics. They only=
quote a very good figure for external inputs. It might be pretty good with=
a pair of quiet external mics.
