Some example YouTube videos showing off the range of quality of segmentation one can get using Segmentino. NNLS Chroma is used as a chroma extractor, by borrowing code from the Vamp plugin of the same name. The beat times are extracted using Davies's beat tracker as implemented in the Queen Mary Vamp plugins, which in turn is based on the QM DSP library. It is similar to Mauch's original Matlab implementation used in the publications, but not exactly the same. This Vamp implementation was coded by Massimiliano Zanoni, Matthias Mauch and Chris Cannam. Furthermore, as with any audio algorithm, the method doesn't work perfectly even if these conditions are actually fulfilled. This method was developed for "classic rock" music, and therefore assumes a few characteristics that are not necessarily found in other music: repetition of harmonic sequences in the music that coincide with structural segments in a song a steady beat segments of a certain length corresponding segments have the same length in beats. This is described in Mauch et al.'s thesis as heuristic of a music editor who tries to make a concise transcription to make orientation in the score easier, and to save space (or paper). This last step is repeated until no more families fit the remaining "holes" in the song that haven't already been assigned to a segment. Now comes the crucial greedy step: having accumulated a lot of families, the families are rated, and the one with the highest score is used as the first segmentation group that gets annotated. Based on this first similarity calculation, an exhaustive comparison of all possible segments of reasonable length in beats is executed, and segments are added to form segment families if they are sufficiently similar to another "family member". A beat-quantised chroma representation is used to calculate pair-wise similarities between beats (really: beat "shingles", i.e. Installation instructions for Mac, Windows, Linux can be found here. Popular free hosts are Sonic Visualiser, Audacity and Sonic Annotator.įor the newest Segmentino plugin downloads, ready to be installed, go to our Downloads page. Vamp plugins can be used with any Vamp host. Version 1.0 was run in MIREX 2013 ( results here). Segmentino is a Vamp plugin for automatic music structural segmentation, based on an algorithm first used in Mauch et al.'s paper on Using Musical Structure to Enhance Automatic Chord Transcription.
