Topic: The Stereophonic Zoom

[KenH]

Just thought I'd start a thread to discuss this paper, which has helped change my approach to recording and improve results.

I used to think that ORTF or DINa was the way to go w/ my mics in general, but after reading (and re-reading!) this document, and trying things like 40deg angle+35cm distance, and 60deg/30cm, my recordings are less boomy, so far.

I also needed a place to post pix of the Crocodile Eye (for measuring the angular coverage segment values of the sound source ) described in the doc, source http://www.soundsscot.com/ 

1st pic is Back view showing the optical viewing eye. The crocodile covers a viewing angle of 180°.
2nd pic is Front view showing the 25mm optical lens and graduations every 10°

Don't think I'd wanna lug this around, but it's pretty cool.

There are numerous references to and suggestions for checking out the Stereo Zoom on this site. It's a great approach and general thought process.

Easy estimation of angles can be done without any extra gear using the 'back yard astronomer' method- a fist held at arms length covers approximately 10 degrees of arc.

Stereo Zoom is so 1984 though, MMAD is now.
