- In Ardour, every <dfn>region</dfn> has a <dfn>gain envelope</dfn>, which is normally hidden. Clicking on the Draw tool will cause all the gain envelopes on all regions to show themselves; these will appear as green lines with square dots (<dfn>control points</dfn>) at the beginning and end of each region. The vertical axis represents gain, with the top of the region representing +6dB and the bottom representing approximately -170dB. By default, the line starts and ends at 0dB; the control points can be moved up and down to change the amount of gain at that point.

- Gain follows the line between control points continuously during playback, and adjusts the gain for that region accordingly. It is completely automatic, unlike channel <a href="@@automation">automation</a>.

- The default gain curve, by itself, is not very useful; in order to have more control over the shape of the gain envelope it is necessary to add extra control points. To add a control point to the envelope, click anywhere in the region where there are no existing control points; it will appear <em>on the line</em> at the X-axis of the mouse's current position in the region.
