Geometric Imaging of Sound

Typical two dimensional (2D) representations of sound can be brought into three dimensions through the use of geometrical imaging.

The image below is a more comprehensive 3D representation of a flute. The shape can be rotated and explored in 3D.

The third image below represents a marimba note. The outer portions show the initial attack; the inner part shows the smooth decay of the note. These images were created by the technique of lagged embedding (the pseudo-phase-plane technique).

These images were created at Sydney VisLab with AVS.
