    • A music generation engine automatically generates musical compositions by accessing musical sections and corresponding properties including similarity factors that provide a quantified indication of the similarity of musical sections to one another (e.g., a percentage of similarity). A sequential relationship of the musical sections is then determined according to an algorithmic process that uses the similarity factors to assess the desirability of the sequential relationship. The algorithmically created musical composition may then be stored, such as by rendering the composition as an audio file or by storing a library file that refers to the musical sections. The created musical composition may include layers respectively having different audio elements such that the created musical composition has a first dimension along a timeline and a second dimension that provides a depth based upon the presence of different audio elements. The presence and absence of audio elements along the timeline can be based upon the value of an intensity parameter, which may be an intensity envelope that is predetermined or automatically generated based upon user specifications.
    • 音乐生成引擎通过访问音乐部分和相应的属性来自动生成音乐作品,包括提供音乐部分彼此的相似性的量化指示(例如,相似度的百分比)的相似性因素。 然后根据使用相似性因子来评估顺序关系的可取性的算法过程来确定音乐部分的顺序关系。 然后可以存储算法创建的音乐作品,例如通过将作品呈现为音频文件或通过存储引用音乐片段的库文件来存储。 所创建的音乐作品可以包括分别具有不同音频元素的层,使得所创建的音乐作品具有沿着时间线的第一维度和基于不同音频元素的存在提供深度的第二维度。 沿着时间线的音频元素的存在和不存在可以基于强度参数的值,强度参数可以是基于用户规格预定或自动生成的强度包络。
