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

Im using it to make a video out of a song, (ffmpeg -i input.mp3
-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

Can someone help me ?
