Systems and methods for chronologically ordering digital media and approximating a timeline of an event

A method for synchronizing digital audio and/or video tracks recorded at a same event, the method comprising:

• accessing input digital audio tracks that are storable in a database, wherein the input digital audio tracks comprise a list of original recorded digital audio tracks from original recorded digital videos that were recorded from multiple digital sources at the same event;
• extracting at least one feature from each digital audio track of the input digital audio tracks,
• constructing, based on the at least one feature, a peak map for each digital audio track of the input digital audio tracks;
• detecting a match between at least two digital audio tracks by performing a cross-correlation of the peak maps of the digital audio tracks of the input digital audio tracks;
• computing a confidence value of the match;
• selecting at least one link between the at least two digital audio tracks of the match, wherein the at least one link comprises a confidence value above a predetermined confidence threshold;
• and
• creating an output group based on the at least one link, wherein at least two digital audio tracks belong to the output group if the at least one link exists between the at least two digital audio tracks.

A non-transitory computer-readable medium with instructions stored thereon, that when executed by a microprocessor, perform a method for synchronizing digital audio and/or video tracks recorded at a same event, the method comprising:

• accessing input digital audio tracks that are storable in a database, wherein the input digital audio tracks comprise a list of original recorded digital audio tracks from original recorded digital videos that were recorded from multiple digital sources at the same event;
• extracting at least one feature from each digital audio track of the input digital audio tracks,
• constructing, based on the at least one feature, a peak map for each digital audio track of the input digital audio tracks;
• detecting a match between at least two digital audio tracks by performing a cross-correlation of the peak maps of the digital audio tracks of the input digital audio tracks and/or estimating a delay between at least one pair of digital audio tracks of the input digital audio tracks, wherein the delay comprises a time difference between the at least one pair of digital audio tracks that received a maximum value in the cross-correlation of the peak maps;
• and
• creating an output group comprising the at least two digital audio tracks and/or the at least one pair of digital audio tracks.
