摘要： A library of audio segments of a song is generated by receiving recorded tracks that include a complete performance of or a composition of unique portions and repetitive portions of the song, segmenting a select track into intervals, analyzing each interval to characterize the interval, comparing each interval with subsequent intervals of the select track to identify repetitive content in the song, identifying a select interval from a set of repeated intervals from the select track and storing the encoded representation of each of the select intervals from a corresponding set of repeated intervals in the library. Intervals can be characterized by frequency analysis, cross-correlation of a waveform, by a trained ear or by analysis of a musical notation corresponding to the song. Intervals for compression can be based on beats, that is, the time for a designated note, notes, a measure, or multiple measures. One or more unique measures can be encoded for additional compression. An interface exposes information from the library that enables the user to control a rendition of the song.

摘要翻译： 通过接收包括歌曲的独特部分和重复部分的完整演奏或构图的记录轨道来生成歌曲的音频片段，将选择音轨分割成间隔，分析每个间隔以表征间隔，比较每个 间隔与选择轨道的随后间隔以识别歌曲中的重复内容，从选择轨道的一组重复间隔中识别选择间隔，并且从所述选择间隔中的每一个重复间隔的编码表示从 图书馆。 间隔可以通过频率分析，波形的互相关，训练的耳朵或通过对与歌曲相对应的音乐符号的分析来表征。 压缩间隔可以基于节拍，即指定音符，音符，度量或多个度量的时间。 可以编码一个或多个唯一的度量来进行额外的压缩。 界面公开了库中的信息，使用户能够控制歌曲的演绎。
