Re: [Sursound] B format recording

I routinely use ProTools to mix B+ . All the decode is done in a separate computer that takes l/r and B format and will decode to 10, 12 or 16 positions. If you do not use Z is will do horizontal only ambisonics. ThomasChen -Original Message- From: Dave Hunt To: sursound@music.vt.

No personal offense taken. I am used to this misattribution! (one thing that occurs to me is that people maybe do not read The Absolute Sound so much as I might have thought. This is one reason why I started www.regonaudio.com though this particular item is not up there)/ I guess I am more amaze
