Little Mix - Move (empty arena) 

There was this app named MixPad (not sure if it still exists, I no longer do these edits) that lets you do it. Anyway, you can do this in any audio editor, the effect is called 'reverb'. Hope that helps! :)

PineappleHead 777 thank you!

PineappleHead 777 sorry to bother you i have made a few edits but i dont know how to save them to my camera roll :(

Everything Nutella you mean just audio edits or actual videos with the audio? :)
