Envelope graphs
Envelope graphs are used to configure the shape of frequency or amplitude envelopes applied to audio
waveforms.
Understanding the envelope graph
To use the envelope graph, you must first understand what it represents. In the previous example, the
horizontal axis represents time, with the leftmost point representing the start of the selection and the
rightmost point representing the end of the selection. The vertical axis represents either amplitude or
frequency, depending upon the operation.
Moving an envelope point
1.
Drag an envelope point to a new position.
2.
Release the mouse button. The point is repositioned and the envelope adjusts.
Moving multiple envelope points
1.
Starting in an unused area of the envelope graph, drag the mouse to create a selection box containing all
points to be moved.
2.
Release the button. The selected envelope points are display in red.
3.
Drag any of the selected envelope points to the desired position. The pointer displays as a multi-
directional arrow and the selected points move together.
