Can I use the sounds in the Freesound add-on library commercially?

The Freesound library contains sounds with mixed licenses for commercial use. If you intend to use the sounds commercially, make sure to choose the CC0-license option when adding the Freesound add-on library. This can be done at any time by right-clicking the Freesound library in the Sounds-tab and choose ‘Creative Commons 0 only’.
