Abstract:
1. A method for generating records for a database for a collection of audio recordings, the method comprising: obtaining a first sequence of track durations for each recording in the collection of audio recordings; generating a rounding entry for each value in the first sequence of track durations by rounding each value in the first sequence of track durations in a selected direction to a nearest integer multiple of a rounding factor when the value is not within a predetermined range of an integer multiple of the rounding factor; generating a first rounding entry and a second rounding entry for each value in the first sequence of track durations when the value is within a predetermined range of an integer multiple of a rounding factor, the first rounding entry being the value rounded in the selected direction based on the rounding factor and the second rounding entry being the value rounded opposite the selected direction based on the rounding factor; wherein the predetermined range is an integer division of the rounding factor; and storing each rounding entry in a first database, wherein the first database stores a plurality of permutations of track duration sequences resulting from the values that have been rounded.
