17. Have Ambisonic decoders been manufactured commercially?
Yes.
Minim Electronics Limited marketed a range of three decoders, the AD
7, AD 8 and AD 10, and also a printed circuit board module for
enthusiasts to incorporate into their own projects.
IMF Electronics assisted in the development of Ambisonics and
manufactured a decoder, the D20B. Part of the company was resurrected
under the name TDL Electronics Limited, but it is unlikely that they
have had any interest in Ambisonics.
