Concerto for public transport orchestra in four movements

The algorithms regularly receives data about the movement of public transport from a server in Latvia, which provides this data to several transportation services in several cities in Russia and the Baltic States, and interprets (sonificating) this data as a sounds.

The algorithms generates an array of tone frequencies within a equally tempered scale:

  • for the first part: from the small octave note D (146.8324 Hz) upwards in a quarter-tone scale (24 notes per octave);
  • for the second part: from the note A of the contra-octave (55.0000 Hz) upwards in semitone scale (7 notes per octave);
  • for the third part: from the note in A of the contra-octave (55.0000 Hz) upwards in an eighth-tone scale (48 notes per octave);
  • for the fourth part: from the B note of the first octave (493.8832 Hz) upwards in 300-tone scale (300 notes per octave);

In the following, the algorithm will map each of the tones to a velocity in km/h such that the higher the velocity, the higher the tone.

The first two parts calculate the average traffic speed and monitor its change. If the average traffic speed in the city increases, the distance between tones over time decreases (tones are played more often). In case the average traffic speed decreases, the distance between tones increases (tones are played less frequently).

In the third and fourth parts, the distance between tones is fixed.
