But if I were approaching it as a stat problem, I would define "silence" based on some bimodal modeling of the collapsed audio file. Then, having defined duration of tracks that are "silent", define long periods of silence as a track break, and take the midpoint as the time break. | |

It works on some but not this one for instance: imgur.com/a/82E4JFA I'm having better luck (but not 100%) using a method that looks for a grouping of 5 values where the median value is > 7x the minimum of the preceding set of values. It worked on a bunch then failed on this: imgur.com/a/ubsWcC0 (the purple line is the updated alg in each) | |
