Multimedia search and indexing for automatic selection of scenes in a media by analyzing frequency ranges

In a signal processing system including a multi media search and indexing system for automatic selection of scenes or sounds recorded in a media for replay in other contexts, a method for setting audio clip levels in analyzing the media for a set of frequency ranges of interest for replay, comprising the steps of:

• (a) selecting an audio clip level for each frequency range as indicative of a scene or sound of interest in the media;
• (b) selecting a time interval in seconds leading an audio level exceeding the clip level;
• (c) selecting a time interval in seconds following the exceeded audio clip level;
• (d) repeating steps (a), (b), and (c) for each frequency range;
• and
• (e) recording and relating each scene of interest exceeding the audio clip level to the index in the media in steps (a), (b), and (c).

A program medium, executable on a computer system, for automatic selection of scenes or sounds recorded in a medium for replay in other contexts, comprising:

• (a) program code in a medium for selecting desired frequency ranges of interest in the media as indicative of a scene or sound of interest;
• (b) program code in a medium selecting the granularity or length of the selected frequency ranges;
• (c) program code in the medium determining the number of analysis intervals on the media in the selected frequency ranges and granularity;
• (d) program code filtering the media for the desired selected frequency ranges;
• and
• (e) program code in the medium measuring the audio level for the selected frequency ranges in each interval.
