This add-on is specifically made to make the workflow simple when using freesound.org samples when doing music live-coding with the music programming language Strudel. To do this you need to find the cdn-link where the mp3 is hosted, and fetch that in your Strudel patch. This software was made within a research project at Chalmers University of Technology in Göteborg, Sweden, to teach programming to kids.
This add-on might have other use-cases that the developer has not thought of.
