How to use this tool

  1. Enter tracks, total seconds, crossfade.
  2. Use consistent units shown beside each input. Run the calculation and review the assumptions below.

Try this example

{
  "tracks": 10,
  "total_seconds": 2400,
  "crossfade": 5
}

Accuracy and scope

Assumes each adjacent pair can support the overlap and no gap or trimming; individual track lengths are not checked.
