Comment:

 ͏    https://ffmpeg.org/ffmpeg-filters.html#showwavespic

 ͏    Cannot reproduce?
 ͏    `ffmpeg -y -v debug -hide_banner -nostdin -nostats -f lavfi -i
 "sine=d=0.1" -lavfi "showwavespic" "!.png"`
 ͏    `ffmpeg -y -v debug -hide_banner -nostdin -nostats -i "s.wav" -lavfi
 "showwavespic" "s.png"`
 ͏    (tried very much your original command too)

 ͏    What's the FFmpeg version?
