    • 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. The present invention provides a format in which all of the parameters 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 and modulators, 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.
    • 提供了一种音频数据格式,其中使用声音样本和确定对声音样本的修改的发音指令的组合来描述乐器。 仪器形成第一初始层,第二层具有可以由用户定义的预设,以提供附加的铰接指令,其可以在仪器级别修改关节指令。 使用各种参数指定关节指令。 本发明提供了一种格式,其中所有参数以与物理现象相关的单元来指定,并且因此不与用于创建或播放音频样本的任何特定机器相关联。 发音参数包括发生器和调制器,其提供实时信号和发生器之间的连接。 参数单位以感性添加单位指定,使数据便于携带,易于编辑。 新单位被定义为全部给出感知加成参数。
