How to remove "Writing library" from .mp3?

I am trying to encode .mp3 without encoder information ("Writing library"), but it fails. I already try:

1. ffmpeg -i test.wav -map_metadata -1 -map_chapters -1 test.mp3
2. ffmpeg -i test.wav -write_xing 0 -id3v2_version 0 test.mp3

and

3. ffmpeg -i test.wav -write_xing 0 -id3v2_version 0 -map_metadata -1 -map_chapters -1 test.mp3

but "Writing library : LAME3.100" still exists...

What do I need to do to remove this metadata? (Writing library)

Just add -metadata 'Writing library'='' to whatever you do, just before output filename.

Example:

ffmpeg -i test.wav -metadata 'Writing library'='' test.mp3
