Abstract
Sound must be displayed so that it can be explored and described. The most intuitive way to visualize sound is to build a time × amplitude plot. Several options to produce an oscillogram are given, so that high-level graphics including color tuning, text annotations, and image overlays can be obtained. The computation and display of the absolute and analytic amplitude envelopes are also explained. The key principle of a window sliding along the sound used for smoothing or discretization of the waveform is also detailed.
