Ribbons in a small roomgreenspun.com : LUSENET : To Hear Ourselves As Others Hear Us : One Thread
Hi James, I'm still working through your book, update coming.
I know how you feel about the technical issues, but I could use some help as I'm getting crummy results with my Coles ribbons. I have a piano in a 13x24 room, and in Blumlein configuration it sounds awful. Some recording engineers have said they don't believe a Blumlein pair can be closer than 20 or 30 feet to the piano, because of the small angle of incidence, and it's probably impossible to record classical piano in a room this size.
Any thoughts? I'm considering selling the ribbons, I'm having so much trouble. But I'd like to make this work.

"Some recording engineers" are wrong. Moreover, I have no idea what "small angle of incidence" means; and I suspect that they don't, either. I have Blumlein-recorded piano from five feet away and from 10 or 12 feet; but 20 would be extremely far except in unusual circumstances. The smallness of your room is indeed likely to be a limiting factor on the quality of sound you can get; but you should Not be getting anything that sounds "crummy." In fact, in any room that's "acoustically small" (small relative to wavelengths; thus, not just your liv/rm but small recital halls, too), there's a Big *advantage* to figure-8 mikes over all other patterns. I can't take more than about five minutes on this, but send me a sample one-minute .wav file at 16/44. The problem is certainly not the Coles mikes..... Oh, wait; are they 4040s? If so, I have no idea whether they're the problem; have never heard them. I was assuming 4038s. I hope you're aiming the mikes correctly----for instance, if they're aimed (in the vertical dimension) at the underside of the lid, the sound will be hollow. Remember that there is a LOT to know about recording. // But I WISH you'd be using this time and energy for your Music work, not for fooling around with audio!

Never heard back from you. Are you using the book's techniques? Did you solve the "crummy sound" problem?

Hi James, Sorry, I'm on a long business trip and the music is suspended until I get back. I'll get back to it and let you know.
