High order ambisonics testing
Are there any freely available samples of 2nd- or 3rd-order ambisonic recordings?

Not that I know of unfortunatly  . It's to my understanding that ambisonic recordings can only be made using a Soundfield Microphone (a lot of recording engineer's are starting to buy these). It's very distinct in the way in which the microphone works seeing that it takes into account a X,Y,Z, and W axis seperatly.

Those are mikes for B-format, which is 1st-order. 2nd order requires 9 mikes. 3rd order requires 16.

I understand now, isn't their also a G-Format too? I know about the B-format but the lines after that are kind of blury. The G-Format doesn't require a seperate decoder correct? It's definitely the future for surround, but it's bad enough the average user doesn't even use 5.1 setup correctly.

http://www.cantares.on.ca/cds.htm I was browsing around and this is all I could find unfortunatly  .  I will keep searching though. It's very easy to find software related to ambisonic and research, but recordings are hard to come by

Alan Parsons Project's Stereotomy is UHJ encoded (Ambisonics), which is 3-2-3 matrxied 1st order horizontal-only Ambisonics (that is W,X,Y only, but having the Z-information won't help you unless you have a suitable 3D decoding rig and speaker setup).

Also, most of [a href="http://www.wyastone.co.uk/nrl/]Nimbus Records[/url] CD's are UHJ encoded, and they decode beautifully when using a UHJ decoder.  Nimbus recently also released a DVD-A series, which has the Ambisonics decoded sound on it:  Nimbus DVD Music
