As in several previous meetings, MPEG had a brainstorming session on future audio activities. At this meeting, the potential work areas were driven by potential HEVC application scenarios. The main aspects are large screen, small viewing distances and hence near field audio perception. They include home cinema requiring to render a multi-channel audio program onto a different number of speakers or to define wavefield synthesis. Other applications include real-time communications, camcorders, storage (random access issues), 3D video and telepresence as well as personal 3D video. Requirements focus on resolution of sound source localization, enhanced spatial audio for stereo displays as well as standardized downmixing. Results of the current discussion and first requirements are summarized in N11865 Audio for High Efficiency Video Coding.
Young members of the audio and requirements group are encouraged to further elaborate their ideas. The audio group is encouraged to enlist more universities in their activities.
