Patent ID: 8332757

Claim:
A computer-implemented method, comprising: receiving one or more media elements including audio data, the one or more media elements having associated parameters; generating a clip for each media element, each clip being a visual representation of an associated media element; displaying an interface for representing each clip relative to a timeline; responsive to a first selection of a first audio parameter, displaying in the interface a first parameter lane associated with a first clip and having associated first parameter lane control elements, wherein a particular first parameter lane control element is associated with a first shape and wherein the first shape indicates a property of the particular first parameter lane control element; responsive to a second selection of a second audio parameter, displaying in the interface a second parameter lane while the first parameter lane remains displayed, the second parameter lane being associated with the first clip and having associated second parameter lane control elements, wherein a particular second parameter lane control element is associated with a second shape, wherein the second shape indicates a property of the particular second parameter lane control element, wherein the first and second shapes are different and the respective indicated properties are different, and wherein the first shape indicates a hold keyframe between parameter lane control elements and the second shape indicates a linear interpolation between parameter lane control elements; receiving an input modifying one or more of the first and second parameter lane control elements; and adjusting the parameters of the media element associated with the first clip according to one or more properties of the first and second parameter lane control elements.
