    • A system is disclosed which allows people who enjoy listening to musical recordings to find new musical recordings that are similar target musical recording. The system uses a model of alikeness (105) which is based upon empirical observations of human perception of likeness between pairs of songs. The humans judge a representative sample of music (101) to build the model (105). Then other musical recordings (109) are applied to this system which extracts parameters (104) from the content of each recording and applies them to the model (105) to compute the differences between the parameters of the new recording and parameters developed for the model to place them in a data base of parameter differences (107). By allowing a user to select one of the recordings from the data base for which parameters have already been extracted, the system can efficiently work with a large number of recordings. A further efficiency improvement is achieved by precomputing differences between the target recording and other typical recordings within the data base. A large data base is efficiently managed by partitioning the data base into clusters.
    • 公开了一种允许欣赏音乐录音的人们找到类似于目标音乐录音的新音乐录音的系统。 该系统使用一个alikeness模型(105),该模型基于对人对两首歌之间相似性的感知的经验观察。 人类判断音乐的代表性样本(101)来建立模型(105)。 然后,其他音乐录音(109)被应用于从每个记录的内容中提取参数(104)的该系统,并将其应用于模型(105),以计算新记录的参数与为模型开发的参数之间的差异 将它们置于参数差异的数据库(107)中。 通过允许用户从已经提取了哪些参数的数据库中选择一个记录,系统可以有效地进行大量记录。 通过预先计算目标记录与数据库中的其他典型记录之间的差异可以进一步提高效率。 通过将数据库分区成群集,可以有效地管理大型数据库。
