MetatOGGer is the first tagging tool which boasts a dynamic and vector user interface, based on Windows Presentation Foundation (WPF). The operations can be done manually or automatically by seeking information in a local database of several hundreds of thousands of discs (from MusicBrainz). MetatOGGer makes it possible to rename, tag and easily classify your Ogg Vorbis, FLAC, Speex and MP3 files.You can add the support of other audio format via plug-in. Is there anything I'm missing? Any ideas? I need this for improving bulk insertion performance in my RBush JavaScript library (an efficient R*-tree implementation).MetatOGGer makes it possible to rename, tag and easily classify your Ogg Vorbis, FLAC, Speex and MP3 files. Kind of a generalization of unordered partial sorting problem.īut I have a gut feeling that there might be a simpler and more efficient approach to the problem. An significant improvement may be to apply divide-and-conquer approach to quickselect, first sorting the array into two groups, then sorting each half, etc., until we have M groups. sort a million items into 5 groups).Ĭurrently I've settled on using the quickselect algorithm (specifically, it's Floyd-Rivest variation) that sorts an array into 2 unsorted groups, and then applying it M-1 times.

But it's inefficient, especially if the number of groups is much smaller than the total number of items (e.g. The easiest way is to just sort the whole array. I'm looking for an efficient algorithm to perform the following: given an array of N items, sort it in a way so that items come as M equal groups, where each group is unsorted, but groups are sorted between each other (all elements in one group are less than any element of the next group).
