Ok, so implementing @koogs changes are not enough, as you get back to the business of empty recorded files. However, that gave me an idea (Thxs @koogs) which I tested and sort of works. I mean, it only works for mp3 files but not for wav files. However, I tried a second idea, and it might work for you although it doesn't seem to have much control over audio when it is being played. That is what I labeled second solution using sampler objects. It works for both mp3 and wav files (tested).
INSTRUCTIONS: In the code, define your file to play. When you run the sketch, press r to begin recording, r again to stop recording. Don't forget to press s to save the file to an audio file which will be located in the data folder.

FIRST solution: Only mp3

SECOND solution: Works for both wav and mp3
