Re: [Sursound] Sound localisation techniques
I use 16 speakers in a dual hexagon(up and down). I think that spacing at 45 degrees will give good results. I also space the two on each of the r walls of the room. I think the corners are bad because of the time differential between the speakers i.e. length of the radius from the center.

[Sursound] B-Fromat microphone
Hello all, I've been experimenting with making a native B-Format mic using 3D printed parts. I've done some recordings with it and I was wondering if people here with ambisonic playback systems could give one of them a try. Any comments will be very appreciated. A photo of the mic: http://www.hcenteno.net/extras/b-format_mic.jpg Link to binaural decode and link to B-Format file (in the description): https://soundcloud.com/hcenteno/wow-what-is-that-papa Change the level of the W channel to taste (the W capsule is more sensitive than the rest so I had to reduce it to what sounded good to me).

Re: [Sursound] B-Fromat microphone
Bravo on the mic! I have played your file (as my set up is restricted to 4.0 horizontal mode, I have only matrixed channels W, X Y). I find it difficult to know at what level to set the W channel, as what appears to be going on all around is (excuse me, no offence intended!) rather chaotic. Could you provide a file of someone talking at the front, rear and sides of the array? This would enable calibration of the relative levels of WXY. I spent some time doing this with my own pantophonic mic recently and was pleased with the results.

Re: [Sursound] B-Fromat microphone
dear hector what capsules did you use? these look like 10 mm. Zoom h2n uses something similar for the s part of the ms microphone but I have not seen omnis. I like the 3d print. my own version uses six cardioid capsules, but I never completed it. umashankar Date: Mon, 5 May 2014 13:40:45 -0400 From: hcen...@gmail.com To: sursound@music.vt.edu Subject: [Sursound] B-Fromat microphone Hello all, I've been experimenting with making a native B-Format mic using 3D printed parts.

Re: [Sursound] B-Fromat microphone
Hello Umashankar, Yes, they are all 10mm capsules. The bi-directional capsules are EM-183, probably the same as the Zoom H2n, and the omni is a EM-172.
