Here the author of the original post explains why:īasically you are stripping the header of the file by skipping 44 bytes with dd but that value varies from file to file, as it happened to me. This works but the values use in dd are not adequate for every case. "$executable" -I dummy "$argument1" "$argument2" "$argument3" The script below converts all *.m4a files in the current directory to *.mp3. But we can use vlc to transcode it, or rewrite it to another format. Tried it on ubuntu 16.04.Īs pointed out in the comments, the result can be opened in VLC, but not in Audacious.
Install faad if needed sudo apt install faadĭd ibs=1 skip=44 if=yourfilename.m4a of=raw.m4aĪll credits to the author of the link I am pointing to, cause I do not know what I am doing, but I tested it on your bigger file, and it works. I have tried uninstalling and reinstalling the restricted codecs. But it would cost $86 for it, and I need to fix 6 recordings. Also I tried an mp4 repair service and it works so the file should be able to be fixed. Faad returns this error: Unable to find correct AAC sound track in the MP4 file. 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.
