Abstract
A method for attaching metadata includes steps of specifying at least two positions in head portions of bars of music data of music, and segmenting into segments a duration extending between the specified two positions and attaching time-series metadata to the segments.
Claims13
A method for attaching metadata to music data stored in electronic memory using a processor to attach the metadata to the music data, the method comprising:
- specifying two positions in head portions of bars of music data of music;
- segmenting into segments a duration extending between the specified two positions and attaching time-series metadata to the segments using the processor;
- automatically extracting beats from the music data by using a signal processing device to automatically detect beats and by using the processor to extract the automatically detected beats;
- plotting an error, an accumulated error and a phase shift for each beat of the extracted beats on a graph corresponding to an average beat rate of the extracted beats by using the processor to compare the error, the accumulated error and the phase shift for each beat to the average beat rate;
- and
- displaying the graph on a display device.
