The Tetra-Speaker is newly developed 3D speaker system influenced by Michael Gerzon, the pioneer of Ambisonics. In 1971, Michael Gerzon began to experiment with soundfield recording and reproduction, beginning with tetrahedral recordings. His techniques introduced listeners to a new world of experiencing immersive sounds.

​

Unlike Gerzon's focus on reproducing the soundscape, the Tetra-Speaker focuses on reproducing the individual sound source itself. By reversing Gerzon's original tetrahedral recording technique, the speaker is able to replicate the radiation pattern of a single source to a degree that when reproduced, a holographic-like image of the original source may be perceived. This innovative approach opens a new perspective to virtual sources in a virtual environment. The speaker may also be used an electroacoustic instrument, a 3D tool for composers to create immersive compositions.

​

The Tetra-Speaker has been featured in various articles and published for the first time as an AES E-Brief in 2018. It has also been showcased in events such as the 145th AES Convention New York as a poster presentation at the Jacob K. Javits Conventer Center and a live showcase at the NYU Music Technology Research Lab

In May 2019, the Tetra-Speaker won Best Demonstration in the Graduate Music Technology at the NYU Music Technology Open House in conjunction with a colleague on a virtual acoustic system.
