A New Compact 3D Reproduction System: The Tetra-Speaker
AES Convention 145 · Paper 487 · October 2018
Abstract
As 3D audio becomes a prominent field of research in audio technology, researchers continue to develop reproduction methods that will best translate 3D recordings. Reproduction techniques have ranged from unique surround systems to 3D speakers such as the dodecahedron. However, these methods may be complex with its disadvantages. These systems tend to be configured for ambient or surround recordings. In this recent project, a new 3D speaker system was created not only for those surround recordings but also for individual sources. The speaker takes influence from the tetra-microphone structure. Testing for the radiation pattern has yet to be conducted. This project is an ongoing research and explores its use with different single-source recordings as well as creative “moving” audio.
