I am manually subtracting one time from another in labels, in order to notate the distance between one label and another. Can Audacity do this calculation?
If you are only doing a few labels, then the easiest way is to click and drag on an audio track to make a selection, starting immediately above one label, and ending immediately above another. You can tell when you are exactly above the label by a vertical yellow guide line.
You can then read the start / end times (or start and duration) in the Selection Toolbar (https://manual.audacityteam.org/man/selection_toolbar.html)
If you’ve got dozens of lables to check, then there’s a slightly more complicated programmatic way to get the times. Let me know if this is the case.
Or if you have a lot of labels you can export the labels to an excel file and then manipulate the Excel to calculate the intervals.
