Audio processing for extraction of variable length disjoint segments from audiovisual content

A boundary of a highlight of audiovisual content depicting an event is identified. The audiovisual content may be a broadcast, such as a television broadcast of a sporting event. The highlight may be a segment of the audiovisual content deemed to be of particular interest. Audio data for the audiovisual content is stored, and the audio data is automatically analyzed to detect soft-entry points identified as low spectral activity points and/or low volume points in the analyzed audio data. A time index within the audiovisual content, corresponding to the soft-entry point, may be designated as the boundary, which may be the beginning or end of the highlight.
