Need help with my app

Hello,

The app is infuriating me, I am trying to edit a simple fun video on my iPhone to send on for somebody…

After understanding how it appears to work I can’t get rid of the incessant beeping of the drone,I went through many resources and also checked App Video Content but did not get any help. I have the generic music playing but the beeps can be heard… I have turned down the volume so that just the music plays but when saved it reverts back.

Please help!!

Any help will be appreciated.
Thank you.
