You don’t need to “establish a license” to receive copyright protection in most jurisdictions (anymore).

Unless they specifically grant a license to the general public (such as Creative Commons) or they release a work into the public domain (in countries that know the concept), the copyright is with its creator.

This only applies to copyrightable works and there are many other edge cases, though.

I assumed these aren't copyrightable, based on the lack of creative work I discern in the recordings. Should've clarified that in my question.
