Ok thanks that's helpful, and this idea, the shotgun mic is something i DID try, just thought up the idea myself. it was not selective enough. The parabola for recording birds? good idea.
I think the other idea is to take some junk CDs, line up the holes but space the disks some increasing...
havent tried the dish yet; there needs to be 3 of these that respond about the same (at least 2 to start with) for one thing; and then another one just needs to be pocket sized
This looks like an excellent setup. But in this case its too complex, Id like to calculate the values for the parabolic antenna, make some fixture with cheap items (because having no work for almost 5 months there is no r/d budget) and something to adjust the audio focal point
or maybe a box...

wow, is that what I looked like back before the enlightenment? Where did you find that picture? kind of eccentric and unusual for sure. I mean the long hair, and to not shave for a picture?
OK so its a parabolic mic setup that should work; anyone know a link to the equations for how to calculate the needed size/focal length ?
that reminds me, there is an old dish network dish sitting around somewhere, but would it have the curve needed?
hi
the question is about how can I arrange a microphone such that it has a "line of sight" kind of sensitivity, only in one direction?
What I've tried so far is to place a 5/8" dia tube towards the direction to be measured and the mic is at the other end of the tube. I've found in listening...
