The strict answer to your question is in Gerzon's "The Design of Precisely Coincident Microphone Arrays for Stereo and Surround Sound"
http://www.aes.org/e-lib/browse.cfm?elib=2466 There's a corrected copy at https://groups.yahoo.com/neo/groups/SoundfieldMic/files/Ricardo/. You might have to join. I used to be able to translate da maths to practical stuff but this Millenium my single remaining brain cell has given up. Aaron Heller & Fons Adrieansen are your best bets. You need to know the polar directivity patterns of your 16 microphones and their 'exact' postion. Bet yus guys didn't know that paper was about more than Tetrahedral mikes :) It's just that in da old days, the computing power required was thought impossible eg "the impossible task of 'tweaking' 16 complex (in both senses) frequency responses to get the (unknown) best match to the desired polar diagrams." Today, computing power is (usually) never a constraint and the much greater problem is knowing how to use it. > I am wondering how I go about converting a recording made with a 16 microphone array into B format? ... > The recordings were made using a "microphone array of 16 microphones arranged in 4 staggered rows, spaced such there is a 5 cm distance form each microphone to its immediate neighbors. The array is in a plane which in all recordings is parallel to the ground." _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound - unsubscribe here, edit account or options, view archives and so on.
