Re: [Sursound] Acoustic properties of round rooms ?

Sorry, I should shave before writing. I meant magnetron, not klystron... There is a lot of stuff if you google circular microwave cavities. I havent looked in detail, but they are, as I expected, high Q devices, which is a much better way of putting what I was trying to say earlier in a ra

Re: [Sursound] Acoustic properties of round rooms ?

How far off perfectly circular makes it not a problem? I had no issues when recording in the Union Chapel, Islington, and my mic was pretty central (it was a concert in the round, though sadly before I could record B-format). The latest offering on the "All of Bach" website (BWV 106) is also in

Re: [Sursound] Acoustic properties of round rooms ?

I thought at first of the membrane analysis, which of course involves Bessel functions, and which has been fully analysed in the text books. There is, however, surely a difference between a circular membrane contrained at the edges (and even sometimes elsewhere) and air, which consists of inde
