Transferring recordings from the TuneIn Radio app

My father recently past away and on my local radio station they announce the obituaries of people who have recently past away. I recorded it on the Tune In Radio app. However, i didn't notice until after the clip played that there seems to be no possible way of transferring that audio recordings the the computer (in m case, a Mac.) However, i can't seem to find good way to do it . Does anyone have any suggestions on how to do it?
