The method proposed maps a predefined parameter space to a psychoacoustic perceptual space. Results based on a very large corpus of music are presented. The paper also discusses future areas of research and identifies other avenues of audio applications where this work may be utilized. The MPEG-4 Standard has different types of objects, representing still images, video of rectangular or arbitrary shape, speech, and audio. The signal types can be either recorded or synthesized.
Different objects have their own optimal coder.
There are possibilities for local and remote interaction with the scene, including mechanisms for spatial auralization. The paper highlights how these tools can be used in appliances. Protocols have been defined for carrying virtually every format of audio and video as well as Internet Protocol, files, and various control protocols. This paper presents information about IEEE 1394 protocols and hardware implementations relevant to developers of information appliances. The initial applications of the technology focus on wire replacement scenarios.
