Jeff, You audio sounds pretty good after being filtered. Here is a few things I do. When I have recordings with car noise, I first use the FFT filter to do a ...
... Very good question. Most cars with real alarm systems have them on the top or bottom of the centre of the front windshield, if my observations are ...
... If you are going to that much trouble then fit it with a wireless mic transmitter and leave the cable off. It's a very interesting thought. I may just try...
... I have another method. I first discovered it while looking around at night down in the Florida Panhandle for Pine Barrens Treefrogs. These little white...
... Very good. Much easier to install, a little easier to spot daytime by the other guy, perhaps, but I bet installation is 10 x faster than pole reflectors....

... Dear KN, Try doing this: Put a new battery in and record for 3 minutes and immediately stop recording and pull out the battery. It should be fairly cool if...
Walter, I thought it was you that said you have to get closer to the subject? Frogs recorded with a parabolic reflector sounds rather odd to me. Regards Roger...
Vicky, It sounds like a wonderful opertunity for binaural recording. Unfortunately you only get the feeling of "surround " sound if you use headphones. Roger...
Re: feeling of surround Roger, what you say is not entirely true. If you place two speakers almost directly out to the sides (eg. about 5-6 feet to each side...
... It's always good to do so, but there are limits. Just how many snake infested swamps do you want to wade across each night? To say nothing of the...

... I have noticed the same thing with the lyrebirds I study here in Australia. A very strong wind makes so much noise in the forest that their songs can't be...
Walt, Have you seen a unit of this type yet? http://home.netcom.com/~t-rex/BatDetector.html I had my electrical engineer uncle look at the schematic and...
ok, honest please, no holds barred. Upfront, slam dunk, is requested. Here is an outdoor stereo setup. I am not able to see a hole in the middle. I seem to get...

... Oh, that's really hard, and the materials are exotic, especially the handle ;-) Parabolics are very easy to build, the hard part is getting a dish. I...
... You really have two ways to go that are relatively cheap, the divider like that one, or a hetrodyne receiver. Here's a couple pages that I bookmarked when...
Walter, I did'nt mean to imply you were odd recording frogs. They are a very interestin subject. What I was implying was that using a parabolic recorder for...
Lang, Yes, but you do loose a great deal of the dynamic of the binaural recording. Better than nothing though, I suppose. Regards Roger C. Boughton ... From:...
Walt: I am using AnaBat hetrodyne bat detectors in my research in Hawaii and the Tropical Pacific, they work really well, though they are more pricey than the...

I thought of adding a dish too, but then, how does one aim a dish at a flying bat in the dark? Another easy way to find the focus of a parabola of unknown...
... It's a new challenge. Obviously you want to build a stereo ultrasonic parabolic mic (with the stealth laser guiding accessory). I thought about that too....
Walter, I'm not saying you cannot make a recording, it just won't be the best you can make. The rules of physics relating to parabolic reflectors and their use...
To all, Have any of you out there tried following a bat with a parabolic reflector!!! I don't think you will find it very succesful. They move a little too...
