View source for Type:AudioSourceWaveformMesh

'''AudioSourceWaveformMesh''' is a [[Type:RectMeshSource|RectMeshSource]] that draws a live oscilloscope trace of a mono audio signal inside a rectangle. It is used as the <code>Mesh</code> member of a [[Component:StandaloneRectMesh`1|StandaloneRectMesh]], which supplies the rectangle.

The mesh keeps a short history of the audio from <code>Source</code> and resamples it to <code>Points</code> points, spread evenly from the left to the right edge. The sample amplitude (-1 to 1) is mapped to the height: -1 is the bottom edge, 0 the middle and 1 the top edge. With no <code>Source</code> set the signal is silence and a flat line is drawn across the middle.

The history length decides how much time the width of the rectangle shows. At the default 0.025 seconds it spans one screen of a 40 Hz wave.
