Topic: Micheal Williams Paper Recording Angles & Imaging

[d5]

But the thing which has really helped the most in all this time is exactly what we're talking about here: Prof. Williams' charts, but especially having a clear grasp of the idea behind them--aiming to match the stereophonic recording angle to the expected playback angle.

I've printed a few copies of chart #9 (for cardioids) and put em in my bag along with my trusty protracter

William's Stereophonic Zoom charts that I've seen from his paper (I don't have his book) all show data for spacings up to 50cm.

I'll be doing some spaced omni recordings from a larger distance than I usually record at tomorrow and was wondering what the distance extrapolation would be to narrower SRA's. Anyone know what the spacing extrapolation for narrower angles would be?

I've used spacings of approx. 1 meter (39") in the past with good results, and that will be my starting point, but I'm curious and would like to try and apply his technique here.

GB -

I would guess you can extrapolate the distances.  However, omnis at a great distance?   Why not cards?  What are you recording?

An outdoor music festival.  I'm unsure of how close I'll be able to setup until I'm there.  I'll likely be able to get up front for some act and certain stages and will probably be farther back in 'the section' for others.  Regardless, the omnis sound great out there in the open with no fear of being enveloped in too much room ambiance farther back.

I'll have the ability to go up to around 2m (6') wide.

I've been schemeing on building a 'crocodile eye' to measure the sourch width angle, but have gotten pretty good at the 'back yard astronomer method' of estimating the angle using the width of my fist at arms length.  One fist width = approx 10deg.

GB - here is the page where Williams discusses your situation, but not much.  ;o)

DSatz, thank you.
