Thanks for the replies
There is a lot of discussion on what makes a good mic. for recording in
the environment. Regardless what you are recording on or what you
subject is there would be certain criteria that separates a good mic
from a average one. Some of these are mentioned regularly eg it is
desirable for the self noise to be below 20dB but this just one aspect
of it.
I have a mic that is used on a video camera. Its Specs are
Unidirectional, Frequency response 70- 16 000 but you for get anything
below 700Hz. Output Impedency 600ohms, Sensitivity -68dB and its noisy.
To assist in the poor sensitivity I use a umbrella for a reflector which
many strange looks have come my way. I record on a minidisk mostly birds
which I have to get close as possible to. Then I didn't know what I was
getting but I had to start some where. I'm a little wiser now but there
is a lot of things that still hazy.
Thanks for you patients David
