[FFmpeg-user] personalize show freqs (bar)

[fal856]

Hi, im new to ffmpeg, and i found the showfreqs filter (
https://ffmpeg.org/ffmpeg-filters.html#showfreqs
<https://ffmpeg.org/ffmpeg-filters.html#showfreqs>  ).

Im using it to make a video out of a song, (ffmpeg -i input.mp3
-filter_complex
"[0:a]showfreqs=s=1920x1080:mode=bar:fscale=log:colors=white,format=yuv420p[v]"
-map "[v]" -map 0:a showfreqs.mp4) but i can find in the docs any way to
"personalize" the bars.

For example, i would like to reduce the ammount of bars, and put some
spacing between each other, and if its posible round the corners of the
bars.

Can someone help me ? 

thnks
