Claim 8:
9. A system for selecting an audio event within an audio data to be included in a highlight of the audio data, the system comprising:
at least one processor; and
a computer-readable non-transitory storage medium storing computer program instructions that when executed by the at least one processor cause the system to perform operations comprising:
analyzing, in a time domain, an audio data to detect a high energy audio burst corresponding to an audio event within the audio data;
determining an event time position within the audio data of the audio event;
analyzing, in a frequency domain, a portion of the audio data within a time spread range containing the event time position to generate a spectral distribution of audio in the time spread range, wherein the analyzing includes filtering a spectrogram of the portion of the audio data within the time spread range by extracting, using a two-dimensional diamond-shaped spectrogram area filter, a subset of spectral peaks that form the spectral distribution of the audio in the time spread range;
determining the number of peaks in the spectral distribution of audio in the time spread range; and
in response to the determining that a number of peaks is below a threshold, adding the audio event in a highlight of the audio data.
