How would you translate "Sound Loop"

[Eui-Jee Hah]

Hi,

I was wondering how you would say "30 second sound loop" in French. The 'loop' part is quite important, I would like to convey that it doesn't just end after 30 seconds.

Also is "musique de fond" appropriate for "background music"?

Thank you.

What do you think of "une boucle (sonore/musicale) de 30 secondes"? With the whole sentence it'll be easier to give you a more accurate translation.

You're right, "musique de fond" means "background music".

That sounds just fine. Merci beaucoup.
