Patent ID: 7957547

Claim:
A method implemented in a computer having at least one processor and at least one memory, the method comprising: displaying a first graphical representation of a waveform line; wherein the waveform line represents a spatial location of audio over a duration; wherein the first graphical representation has a first axis representing time during the duration and a second axis representing spatial location of audio; receiving input indicating a particular time point along the first axis; in response to the input, displaying, on the first graphical representation, at a position along the first axis corresponding to the particular time point, a second graphical representation that represents, in at least two-spatial dimensions, the spatial location of the audio at the particular time point; wherein the first axis represents, with respect to the second graphical representation, a first spatial dimension of the at least two-spatial dimensions; and wherein the second axis represents, with respect to the second graphical representation, a second spatial dimension of the at least two-spatial dimensions.
