Then it says do you mean the file that I did put in. ffmpeg returns a “protocol not found” error. Did you mean in.m4a? which is the name of the file, that I typed in correctly. Or I get an error saying protocol not found. I have tried using ffmpeg to get this error, moov atom not found, which looking up does nothing to help solve the problem. I do not know where the recording starts since when I try to make a new recording it is corrupt off the bat. I have tried many tutorials, including editing the hex data of the recording, no luck. But now they are corrupt as soon as the recording is done. Earlier in the semester they recordings were fine. I have been using the default audio recorder that you can install with sudo apt-get install audio-recorder because it was the easiest to use. I have been using Ubuntu on my school computer this year, I usually record the lectures that I can't hope to keep up with the prof, I have permission to do this.
