i am currently writing my bachelor thesis and i had an interview on tuesday. I did a test record beforehand while the participant of the interview was on the phone. It worked out and so i started with the interview. After i finished the interview, my MAC went off due to low battery (16% -.-) and after i restarted the system, the file was still there but there were no waves or anything else, which would indicate that there is something on it. Indeed, i cannot hear anything, have the file and it can’t be that it did not work. I really need the interview asap. Please help me.
