Voice samples have high pitched ringing

I’m trying to do an audition for voice acting but my samples have a high pitched ringing in the background.

Is there a fix for this??? I really wish I could ask this question in a more specific and better way but I’m absolutely green and learning as I go.

Thanks for any help! I really appreciate it.
