Ambiophonics contributors…

Ralph Glasgal – creator through the Ambiophonics Institute of the name Ambiophonics, and prime mover of its development, progressing from a physical barrier through DSP for crosstalk cancellation and ambience convolution.

Robert E. (Robin) Miller III – engineer/pres. of Filmaker Technology who implemented RACE DSP, the Panambiophone, and other Ambiophonics innovations and related demonstration 2D and 3D recordings, scientific papers, and website content.

Angelo Farina – Ambiophonics researcher at the University of Parma, Italy, who used measured inverse impulse responses of speaker pairs using a dummy head to convolve XTC, and of world-renown halls for ambience convolution.

Enrico Armelloni – student of Farina at the University of Parma, Italy, whose doctoral thesis was developed while an intern at Filmaker Technology.

Edgar Choueiri – Princeton space physicist and XTC developer who used sophisticated band-splitting to minimize any coloration when realizing very high levels of crosstalk cancellation even up to 20dB.

David Wareing – early XTC developer who modeled crosstalk cancellation as a single correction impulse based on the speed of sound and the geometry of the average head.

Anders Torger – Swedish developer of “AlmusVCU” Ambiovolver software (XTC, ambience convolution, bass management, speaker position timing) running on Linux PCs.

“The shoulders of giants” applies, upon which stand those above who have advanced the art termed Ambiophonics. While this list would eclipse this writing, it would include the work of the ISVR, Günther Theile, and the authors of commercial implementations by Carver and Yamaha, etc.

Why would an Antarctic explorer spend 20 years on Ambiophonics?


Ralph Glasgal wintered on Antarctica during the International GeophysicalYear; Glasgal Island, off the Antarctic coast, is named for him. He’s reached the base camps of the ten highest peaks in the world. Why would such anadventurer spend twenty years exploring and refining Ambiophonics for home music playback, even dedicating a non-profit institute to the effort ?

Because Ambiophonics recreates the excitement of live music.

Ralph is a lifelong concert-goer, married to a performing pianist. As a physicist, engineer and member of both the Audio Engineering Society andthe Institute of Electrical and Electronics Engineers, Ralph has spent decades perfecting a way to bring the power and majesty of the concertexperience-- into your home. The result is Ambiophonics.

Using curved electrostatic SoundLab Ambiopoles to form an Ambiodipole results in a wider and much deeper optimum listening Area. This single Ambiodipole provides a stage width of some 150 degrees from almost all stereophonic sources.

In back are two pair of SoundLab electrostatic Ambiodipoles: the furthest rear pair reproduces back surround channels of 5.1 or specially made PanAmbiophonic 4.0 surround recordings; the nearer rear pair widens the front stage to almost 180 deg. (Acoustat 1+1s.)

Optional, full-range SoundLab electrostatic panels on two balconies reproduce height ambience derived by convolution from full sphere impulse responses.  Only for those who are really sensitive to overhead reflections in concert halls.
