Étude Aux Chemins De Fer

This graphic score analysis of Pierre Schaeffer's "Étude aux chemins de fer" was made with the Acousmographe. At the top part, we can see the that every new "shell" is a new whistle played in the composition and every picture of a train indeed represent a new (or different) sound recording of a train. The middle section is colored by the intensity of the sound files in the spectrogram (the frequencies in Hz) . And lower, the wave file, showing the audio content with the separation of the stereo image (left and right).
