Sample Recordings
B-format
A number of my recordings using the TetraMic are available for download from Ambisonia. All of my recordings since July 2007 (except the Ceilidh) were done using it. There also a couple of recordings made by Len Moskowitz of Core Sound.Stereo
Below are links to some samples of stereo created from TetraMic recordings using different techniques. I may expand this when other interesting sounds are available. These links are encoded in MP3, using Lame, at a bit rate of 192k. Where the B-format is available on Ambisonia, I have included a link to that.
Blumlein is crossed figures of eight;
MS is generated from a front-facing cardioid and cross-facing figure of eight;
UHJ is generated according to its definition, by Angelo Farina's method.
Cherwell Singers sing "Crossin' Ovah"
This was recorded in the Magdalen Auditorium, which is a general-purpose auditorium with an acoustic biased towards speech - that's to say, it's rather dry, and gives some brittleness at HF. The soprano soloist is well to the left.

Cherwell Singers sing "It was a lover and his lass"
This is a setting by Rutter, recorded in the Holywell Music Room. You get to hear a piano and bass as well as the choir.
Clarke - Untitled number 3
This piece was recorded at The Warehouse - a studio in London. The performer is Nicolas Hodges. The piece is quiet throughout, so you get plenty of opportunity to judge the noise levels - both hiss, and rumble from the air conditioning. This download is much bigger than the others.
