Psychoacoustics of 3D Audio

Lee, H. (Speaker)

Activity: Talk or presentation typesInvited talk

Description

New surround sound formats such as Dolby Atmos and Auro 3D utilise loudspeakers placed at elevated positions, so-called the height channels. These are used for 3D sound panning and enhancing spatial impression. The mechanisms of human spatial perception for horizontal stereo and surround sound are now well understood. However, the perception of vertical stereophony with height channels relies on a fundamentally different psychoacoustic principles. This seminar will introduce past and current research on vertical stereophonic localisation and vertical interchannel decorrelation for vertical spread perception, as well as new 3D sound microphone array techniques and new 2D-to-3D upmixing techniques. The talk will be accompanied with 9.1 recording demos.
