I don't know anything about Blank on Blank, but this might be worth looking into if you're a freelance audio person looking for work.
freelance audio editors with a creative ear who can make rough
interviews shine. Must be able to work remotely and be able to clean
up interviews recorded on cassette or digital recorder. Three-five
minute finished audio pieces include tracks and music, so music
knowledge is a plus–though not required. Pay per interview project.
