A Poe Pondering:  ‘Spatial Audio from Measurement to Reproduction’

Speaker: Mike Roan, Ph.D.

Cube, Moss Arts Center | Interdisciplinary Events

October 31, 2018 at 12:00pm

Immersive audio or 3D sound is seeing rush of interest due to the broad release of VR devices such as the Oculus Rift. To enhance the audio experience in VR, producers are beginning to settle on a technique known as ambisonics to record and reproduce 3D audio. Ambisonics is a full sphere surround sound technique that relies on four simultaneously recorded channels using a special sound field microphone. This talk will cover the basics of ambisonic recording and reproduction including the necessary hardware and software.

Roan is a professor in the Mechanical Engineering Department at Virginia Tech. His research interests include development spatial audio algorithms and human perception in VR environments, particularly related to 3D sound. Prior to coming to Virginia Tech in 2005, he was head of the signal processing department at the Applied Research Laboratory at Penn State. There he developed automated detection and classification algorithms for various applications. He received his BS, Physics(’89), MS, Acoustics ('91) and PhD, Acoustics (’99) all from Penn State.
