Hello, I would like to show an audio meter from an audio file (something like what edit software display or like Audacity display)
I try the showvolume filter, but the result is not what i would like to have. My command line : "C:\ffmpeg-20180329-af043b8-win64-static\bin\ffmpeg.exe" -i "D:\RefSon100Hz_Son_PCM18_03_30_18h21m17s.wav" -filter_complex "[0:a]showvolume=w=340:h=5:o=v:f=1.:p=1.:t=0:m=r:v=0[v]" -map "[v]" -c:v qtrle "D:\resAudioMeter004.mov" My input test file : https://we.tl/X6L69kEWAN Contains : 1000 Hz -12Db, then - 18 db, then 0 Db. If i use the peak option, i have no difference between -12 and -18 db And the "scale" is not what i would like to have (would like to have -12 / - 18 Db more close to the max level If i use the rms option, the scale is very low for all "level", and no differences between -12 and -18 Db. Is there another filter for that ?
