These plots are generated from sound recordings, either a field recording or a piece of music. The golden circle below was a commission based a drum and bass track. The white sound circle is from a field recording I took involving Tibetan throat singing and singing bowls.
Each of the different frequency bands are represented by a circle. The pictures show about half a seconds worth of audio.
