Include in tutorial

I am making an animation tutorial and want to include some audios in the materials attached to the tutorial. The tutorial is paid and the user will be able to download the audios to use in his project.

is this allowed? Do I need to add a license file that the final work is only for personal use?

as another option I am thinking to use and merge multiple audios. For example 1 background music and 3-4 effects and sounds. But not give them separately but as one audio. In this situation will it not be "Standaloneā€.
