Ambisonic FAQ

The long-established Ambisonic FAQ is maintained by Martin Leese.

Ambisonia - downloads of ambisonic material (now closed)

Ambisonia was a site set up by Etienne Deleflie containing much practical and theoretical information about Ambisonics.  It also hosted torrents of ambisonic recordings contributed by a number of people (including myself), as B-format files (.amb) and as G-format files encoded to DTS.  Ambisonia has now closed down, but Etienne is developing a replacement called Sound of Space (qv).

I have made all the recordings that I put on Etienne's sites available here, and also John Leonard's, with his kind permission.  Both .amb and .dts files are provided.


BLaH - real decoder tests

The BLaH trilogy is a group of papers about Ambisonic decoding - based on listening trials - produced by Eric Benjamin, Richard Lee and Aaron Heller.


Gerzon Archive

The Gerzon Archive - Keith Howard has scanned and made available a considerable number of Michael Gerzon's papers, including some of the earlier ones which were previously hard to find.


Michael Gerzon - his early work, with photos

Stephen Thornton was around with Michael Gerzon from the earliest days of his work.  This website gives an account of those days, copiously illustrated with photographs and notes from Steve's diary.  (Also a few photos by me and of me.)


Sound of Space - downloads of ambisonic material

Sound of Space is a new website that Etienne Delaflie is developing to replace the now defunct Ambisonia website; it is currently still in beta, but already has a modest amount of material on it.

The B-format files are in a new Universal Ambisonic format, for which there are at present no players, as far as I know.  G-format files are available in .m4a and .ac3 formats, which are playable on many systems.


Sursound - surround sound mailing list

The sursound mailing list is an active list discussing all aspects of surround sound.  Although at times it seems to be almost solely concerned with ambisonics, this is not its intention, and other surround techniques are discussed from time to time.


Wikipedia

There is an article on Ambisonics in Wikipedia.  It has been extensively updated recently, mainly by by Richard Elen and Martin Leese, and contains links to related articles.

Mirabilis Recordings

I recently discovered a short-lived record label, all of whose fifteen recordings (mainly of organs) were made ambisonically using a single SoundField ST-250 microphone and released as UHJ stereo.  I have documented the recordings that I have been able to acquire or find out about on a separate page here, as the information is not yet available in the UHJ discography.


Innocent Ear

Innocent Ear contains lots of information about recording in stereo (and a bit about surround, but not ambisonics).  The author, Chris Burmajster is a recording engineer, and has a 'purist' approach which tallies somewhat with mine.
