Level envelope
This dialog allows you to create a volume envelope which can be applied
to a selected range or a whole file.
The dialog consists of a waveform view in the middle, with an envelope
curve (initially a straight line) running through it. A vertical ruler displays
the level change in dB, and the horizontal ruler displays the time line. You
can boost the level up to 6 dB and decrease it down to silence.
Basic operation procedure
By adding points to the envelope curve you can create an envelope curve
that will change the volume of the material over time.
1. Double click on the envelope curve to add a point.
A point will be added where you click.
2. If you click on the point it will be selected (red color) and by click-drag-
ging you can move it in any direction.
The curve changes accordingly in the waveform display.
• When you point the mouse in the display (or move a point), the current
position and level change is shown continuously in the field above the dis-
play.
3. You can keep adding as many points as you like to the curve.
You cannot move a point past a another point in the horizontal direction.
4. You can select several points using [Shift] and move them together.
By clicking on the envelope curve itself (not on a point) you can move the whole curve up or
down.
