Abstract
A method for adjusting the sound volume of media clips using volume adjuster lines is provided. The volume adjuster lines are individually set for each clip based on the intrinsic, or absolute, volume values of the clip. In some embodiments, the volume adjuster lines are set for each clip based on the peak value or a calculated loudness equivalent of the clip. A user can move the volume adjuster line to set the absolute sound level of a clip. The volume adjuster lines can be hidden in some embodiments. In these embodiments, dragging on any portion of a clip is treated as dragging on the volume adjuster line. Some embodiments provide a deformable volume adjuster line, or curve. In these embodiments, a single audio clip can have several different volume adjuster lines for different sections of the clip where the volume adjuster line for each section is individually adjustable.
