6 – 130 Editing in the Wave window
When the Loudness envelope display mode is selected, the “Y” axis is
logarithmic, not linear like in the waveform display.
The vertical zoom slider will change the scale rather than a zoom factor. By displaying a
larger scale, very small volume changes can be viewed.
All standard editing operations, i.e. selecting, cut/copy/paste, etc., are
available, except drawing with the Pencil tool.
About the curves
Up to four different curves can be shown simultaneously in the Loudness
envelope display. These curves have different colors and represent the
average loudness of the signal in different areas of the frequency spec-
trum. This can be useful to visualize where in the frequency domain the
loudness is “spread” at a given time, or to display the loudness of a spe-
cific part of the spectrum. The curves can be shown individually or in any
combination.
Which curves are displayed, and what frequency area they represent is
set in the Loudness envelope options dialog (see below).
