All of these recordings were recorded with a single OctoMic.
Rob Anderson (Rob Anderson On-Location Recording Services) accepted Core
Sound's offer of an OctoMic second-order ambisonic microphone to record
Stile Antico's performance
at Music Before 1800 in NYC.
We decoded the OctoMic recording to Blumlein, binaural and to three
coincident second-order hypercardioids pointed at -45, 0 and +45. (The
OctoMic recording could also be decoded to full immersive surround sound
(including height), headtracked binaural, and many others.)
For the Three Hypercardioids decode, the center microphone was mixed at

And finally, for comparison, here's the same performance, but made
with Rob's ORTF array of two high-end mono mics:

The Angelica Women's Chamber Choir (angelicavoices.org) recently
performed in concert at the Church of St. John Nepomucene in NYC. A
single Core Sound OctoMic second-order ambisonic microphone was used to
The room is large, with a six second reverb period - direct sound
dissipates very quickly. That usually makes recording a demanding
effort. It's much simpler to get a good recording with OctoMic, because
of its very tightly directional patterns, with almost no backlobes.
The choir was arranged in a semi-circle with the OctoMic at the
center. A theorbo was also positioned in the center, but deeper into the
semi-circle. And two recorders were played from the right side.
Below are links to recordings of "Gaudete gaudio magno". You can
download files that have been decoded to stereo (two virtual microphones
- second-order), stereo (three virtual microphones - second-order), Blumlein
(first-order), and binaural (second-order). Or you can download the second-order B-format file and decode it yourself.
And here's Lumen by Abbie Burt Betinis (b. 1980). For

Vid Sontest records ambiences in VR360. He recently recorded a
bicycle bridge in Belgium, using his OctoMic for the audio. You can hear
the resonance of the metal bridge, bicycles, walkers, trains, birds,
frogs and the river.

Phillip Westbrook has been recording a choir with an OctoMic. Here's
a link to a 2nd-order ambiX B-format file of the choir, accompanied by an
orchestra, singing "America The Beautiful" in a mid-sized church.
We think that it's a wonderful recording!
Phillip also created a wonderful 360VR 8k video of a gondola ride in
Venice using OctoMic:
