Tom, I know what you mean. There is never enough time. But get out
recording! You can=B4t do good tech without listening anyway.
A clearifying to Bruce:
Cardioids: Yes, the membrane of a cardioid will move less than the
membrane in an omni. But you will probably get a better ratio between
traffic/atmo noise and signal. So =94gain=94?? (note the word =94probably=
=94)
I am busy developing a new stereo parabol which doesn=B4t make any sense
at all, but sounds great so far.
Is it a =94good product=94? I don=B4t know. Measurements are within reasona=
ble
limits, the rest is a matter of taste. Birds will start making sounds
here at the end of January and after listening to hours and hours of
test recordings I will know around the middle of May.
