摘要： MIDI-generated audio streams(232) or other input streams of audio events (241) are perceptually associated with specific locations in 3D space with respect to the listener (260) A conventional pan parameter is redefined so that it no longer specifies the relative balance between the audio being fed to two fixed speaker locations (260, 270, 280) Instead, the new MIDI pan parameter extension specifies a virtual position of an audio stream in 3D space (270) Preferably, the relative position of a single audio stream is set along a predefined arc in 3D space (260, 270, 280).

摘要： An audio data format in which an instrument is described using a combination of sound samples and articulation instructions which determine modifications made to the sound sample is provided. The instruments form a first, initial layer, with a second layer having presets which can be user-defined to provide additional articulation instructions which can modify the articulation instructions at the instrument level. The articulation instructions are specified using various parameters (78). The present invention provides a format in which all of the parameters (78) are specified in units which relate to a physical phenomena, and thus are not tied to any particular machine for creating or playing the audio samples. The articulation parameters include generators (86) and modulators (88), which provide a connection between a real-time signal and a generator. The parameter units are specified in perceptually additive units, to make the data portable and easily edited. New units are defined to give perceptual additive parameters throughout.
