To convert audio mp3 to MP4 by ffmpeg, use the following command

ffmpeg -f lavfi -i color=c=black:s=1280x720:r=5 -i audio.mp3 -crf 0 -c:a copy -shortest output.mp4

Description

This generates mp4 formatted video with blank black background with the color source filter instead of using an image.

Since it is just black video this is one case with lossless mode (-crf 0) will have a smaller file size than the default lossy mode.
