    Hello. I have noticed that in some movies the audio decreases a lot in some scenes. This happens with the MPV and MPC-HC players. However with MPC-BE and Potplayer does not happen (all configured with normalization enabled). I attach a fragment of a movie. The decrease of the audio is noticeable from the 12 second, when they start talking.

    I would like to know what is the reason for this decrease in audio and if it can be changed in MPV, which is the player that I use the most.

    Code:
    mpv fragmento.mkv -af dynaudnorm=f=10

    Thank you. It works but the normalization does not work so well. Which parameters are the best for a more stable normalization?

    You need to explain more what "stable" normalization means.

    In some movies I notice ups and downs in the audio. As if in some scenes the normalization (dynaudnorm) would not work as well as it should.

    Before, I had it configured like this

    af=lavfi=[loudnorm=I=-25:TP=-1.5:LRA=1]

    and the normalization worked very well except for those audio decreases that I have noticed in some movies.

  6. dynaudnorm and loudnorm are two different audio filters. Can you please be more specific?

    With this configuration it seems that I no longer have problems

    Code:
    af=lavfi=[dynaudnorm=f=75:g=25:p=0.55]
    thank you
