PlaySOM - Intuitive access to Music Archives
Subsequent to audio feature extraction the extracted data is used to train a self-organizing map (SOM), in order to create a two-dimensional map of clustered music, the basis for intuitive user interfaces. The PlaySOM and PocketSOMPlayer applications both enable users to browse collections, select tracks, export playlists as well as listen to the selected songs. The PlaySOM presents a full interface, offering different selection models, a range of visualizations, advanced playlist refinement, export to external player devices or simply playback of selected songs. The PocketSOMPlayer, on the other hand, offers a slim version of the desktop application, optimized for the mobile devices.

The menu bar provides switching to different visualizations, exporting the map as static images or html files, as well as export to the PocketSOMPlayer format. Visualizations can be switched at any time.
By clicking and dragging the mouse a path drawn on the Map. Paths can be drawn anywhere and are allowed to cross themselves. A playlist is created with titles ordered alongside the path.
The Map area of the PlaySOM application can be smoothly zoomed in and out. Additional information is displayed at certain zoom levels.
The amount and type of data displayed is influenced by the zooming level, the higher the zooming level, the more information is displayed ranging from information about the number of songs mapped to a particular unit to detailed information about the tracks.
There is a growing number of additional visualizations available. Also, for each of the visualizations the color representation can be chosen out of a list of color palettes.
