Abstract
Among other things, methods, systems and computer program products are disclosed for presenting a user interface for manipulation of audio waveforms associated with video content. In one aspect, a method can be performed by one or more processes executing on a computer system. Images representing video frames in a first region of a user interface can be displayed. An audio waveform representing audio associated with at least a portion of a video frame can be displayed. At least three audio waveform portions including (i) a first portion of the audio waveform that exceeds a first predetermined threshold, (ii) a second portion of the audio waveform below the first predetermined threshold and above a second predetermined threshold, and (iii) a third portion of the audio waveform below the second predetermined threshold can be graphically distinguished.
