Abstract
Some embodiments of the invention provide a method for controlling the volume of an audio track. This method represents the volume of an audio track with a graph. This graph is defined along two axes, with one axis representing time and the other representing the volume level. A user can adjust the graph at different instances in time in order to change the volume level in the audio track at these instances. Different embodiments use different types of graphs to represent volume. For instance, some embodiments use a deformable line bar.

23. A method for controlling the volume of an audio track, the method comprising:
-
a) representing the volume of the audio track with a deformable graph, wherein the graph is defined along two axes, wherein one axis represents time and the other represents volume level;
b) receiving a modification to the graph;
c) illustrating the modification on the graph as two points on the graph; and
d) based on the illustrated modification, specifying the volume levels of the audio track at different instances in time. - View Dependent Claims (24, 25, 26, 27, 28, 33)

38. A method for editing the volume of an audio track, the method comprising:
-
a) displaying a graph representing the volume of an audio track in a graphical user interface, wherein the graph comprises two axes, a volume axis and a time axis;
b) receiving a modification to the volume of a first portion of the audio track through a click-and-drag operation;
c) during the click-and-drag operation, determining whether the modified volume is within a first threshold of the volume of a second portion of the audio track; and
d) upon determining that the modified volume is within the first threshold of the volume of the second portion, displaying a visual indication of the volume of the second portion. - View Dependent Claims (39, 40, 41)
