How to Upload an Audio File to Youtube?
Youtube does not allow audio files to be uploaded. However, you can easily convert any audio file into a video file using the given audio file and a fixed image as a background. The following works on Ubuntu and any variants of GNU/Linux.
For converting a single mp3 file you can use the following.
ffmpeg -v quiet -i "picture.jpg" -i input.mp3 -shortest -acodec copy output.mp4; done
For converting a batch of files in a folder you can use the following
for i in *.mp3; do ffmpeg -v quiet -i "picture.jpg" -i "$i" -shortest -acodec copy "`sed 's/mp3/mp4/g'<<<$i`"; done
You will need to install FFmpeg in your GNU/Linux system to do this though
