updated
I have modified the Excel sheet so that it will also work on both LibreOffice and (very likely) older versions of Excel.
I also added some functionality that I was very happy to discover, and which will probably be part of my personal workflow for this from now on:
- load the audio file in Audacity
- create labels (timestamps) for the starting points of the songs/segments
- export these labels, and load them into the Excel sheet
I've adjusted the start post with an explanation on this.
