Tartan-ify generates visualisations that shows, in a piece of music, where the similarities and differences are.
Tartan-ify splits the music up into chunks. Every chunk of the song is compared against every other chunk. Each of these chunk comparisons is shown in a matrix, with the time of the song on each axis, with the colour of the block showing the similarity between the two chunks.
Tartan-ify does the comparison by analysing the spectrum of each chunk, using a Fast Fourier Transform, and then taking the sum of the difference in power of each frequency between the chunks.
To use this tool, select a piece of music then select the chunk interval that you want in milliseconds (using the BPM can be useful here), then click Tartan-ify to start the visualisation.
