    • A method is provided for analysing the self-similarity of an audio file. The method involves obtaining the audio spectrum envelope data of an audio file to be analysed; performing a clustering operation on the spectrum envelope data to produce a clustered set of data; for a first portion of the clustered data, performing a string matching operation on at least one other portion of the clustered data; and based on the results of the string matching operation, determining the at least one other portion of the clustered data most similar to said first portion of the clustered data. There is also provided a method of repairing an audio stream received over a network using similarity data to replace damaged or missing portions of data with similar "good" portions of data.
    • 提供了一种用于分析音频文件的自相似性的方法。 该方法涉及获得要分析的音频文件的音频频谱包络数据; 对频谱包络数据执行聚类操作以产生一组聚集的数据; 对于所述聚类数据的第一部分,对所述聚集数据的至少一个其他部分执行字符串匹配操作; 并且基于所述字符串匹配操作的结果,确定与所述聚集数据的所述第一部分最相似的所述聚类数据的所述至少一个其他部分。 还提供了一种使用相似性数据来修复通过网络接收的音频流的方法,以用类似的“良好”数据部分来代替数据的损坏或丢失部分。
