Here’s the thing: Let’s say your text editor interprets the file as ASCII.
Several characters in the ASCII table aren’t printable. The first 32 characters in the table are control characters, so they don’t get displayed on screen as text you could copy and paste. So if you opened an audio file in a text editor as an ASCII file, copied the text, pasted it in another text field, then saved that file, any bytes that were between 0 and 32 decimal would be missing.
