"<a href=""https://www.youtube.com/watch?v=G025oxyWv0E&amp;t=2m06s"">2:06</a> what is Diegetic Audio and what does it have to do with free booting video on Facebook?",(reply>), thank you for the information.,(reply>), Diagetic audio is audio with a visible source, like when the music in a movie comes from a boombox, compared to other audio that has no visible source (like a narration). In a music video this is used to make the audio of the music video different to the singles version so you cant just get the song by ripping it off youtube without an additional awkward break in the middle for some little skit.
