Thank you Mark, and others, who have contacted me with feed-back and questi=
ons.
I will comment all of it here:
Mark: I agree. It handles thunderstorms (?) and wind amazingly well.
For my personal taste, though, I would prefer a recording to also
have a poor little "tjirrrp" from a poor little titmouse....
Yes, The Telinga SSM (SoundScapeMic) will have a fake fur windshield
as an accessory. I need to make it so that one can have the fur both
outwards and inwards.
Yes, to be packed down in a case, the mics can easily be removed from
the rod. When recording, they can point at different directions, just
as you please.
Yes, it is easy to attach a foam baffle or plate between them, to get
amplitude difference.
There have been postings about radiating displays:
All recorders I know of have a radiating display. It is a matter of
how close the mic's are and cable shielding and probably other
factors. Even Nagra had problems with one of their most professional
models and I heard (true?) that they had supplied a transparent
conductive tape to glue on top of the display.
During my some 40 hours of testing the SoundScapeMic with the Olympus
LS-11, I have had no problems with the display. The recorder has been
in a bag about a foot away from the Olympus.
But I don't think it is right to blame either
Sony/Zoom/Olympus/Tascam as the worst. I think "it depends..."
Plus that I sometimes get a bit annoyed when people say that "there
is no way that I can hear this noise, but if I make a spectrum analysis.."
Please... don=B4t look at a Rembrandt with an x-ray camera.
What I have measured is that the Telinga SSM behaves fine down to
0,5v PIP voltage and 2,2kOhm load in a SPL of 100 db and that I see
no need to make extra boxes to increase the driving voltage.
Today was the first day of real spring here! I recorded between 6am
and 9am and counted five new species for the year - Skylark, Tree
Lark, Chaffinch, Redwing and Mistle Trush.
For the ones who want to know what this day sounded like, there are
three new files at
