GNU Audio and Video

 [A gnu listening to music]

Here you can watch video or listen to audio recordings of speeches and other events related to the GNU Project. Many of these recordings are made by volunteers who attend our events, and we thank everyone for sending them in.

Speeches and interviews that are intended for the general public are listed in the category GNU Philosophy and History. Some of them are in Spanish or French, and a few of the recordings have been transcribed and/or subtitled. The transcriptions are published in the Philosophy section.
