System and method for automated video editing

A method for editing media comprising;

• determining a plurality of onsets within a first media item;
• obtaining and recording a plurality of second media items;
• partitioning the plurality of second media items based upon the plurality of onsets from the first media item;
• and
• creating a composite media file by selecting and combining in series a plurality of the partitions from the plurality of second media items based at least in part upon the determined onsets
• wherein determining a plurality of onsets within the first media item comprises:
• obtaining the first media item and partitioning it into a plurality of frames;
• converting information from within the plurality of frames from the time domain into the frequency domain;
• determining a magnitude, in the frequency domain, for each frequency band within each frame;
• filtering each magnitude using a first set of filters and a second set of filters;
• determining an onset has occurred within a frequency band of each of the plurality of frames by comparing outputs of the first and second set of filters;
• and
• determining an onset has occurred within a frame of the plurality of frames based in part on the determination that at least one onset has occurred within a frequency band of that frame by the comparison of the outputs of the first and second set of filters.
