Do You Know What Piece This Is?

Hello guys maybe you can help me figure out which piece this is? I cut it out of a podcast about De Machaut, medieval music, ars nova etc. but they did not include a playlist. It might be a secular work by Guillaume de Machaut or possibly Philippe de Vitry, but even if I know the composer I would really like to know what the title of the work is. 

I will contact the podcast publisher if I cant figure it out. However since they are German and I am not I would rather find out another way, one without having to call on my tremendous German writing skills.

Thanks a bunch!
