  • Normalize audio, then reduce the volume in ffmpeg

    27 octobre 2014, par Steve Sheldon

    I have a question relating to ffmpeg. First here is the scenario, I am working on a project where I need to have some audio with a presenter talking and then potentially some background music. I also have the requirement to normalize the audio. I would like to do this without presenting a bunch of options to the user.

    For normalization I use something similar to this post :

    How to normalize audio with ffmpeg.

    In short, I get a volume adjustment which I then apply to ffmpeg like this :

    ffmpeg -i <input /> -af "volume=xxxdB" <output>
    
</output>

    So far so good. Now let’s consider the backing track, it doesn’t want to be the same volume as the presenters voice, this would be really distracting, so I want to lower that by some percentage. I can also do this with ffmpeg, I could do it like this (example would set volume to 50%) :

    ffmpeg -i <input /> -af "volume=0.5" <output>
    
</output>

    Using these two commands back to back, I can get the desired result.

    My question has two parts :

    1. Is there a way to do this in one step ?
    2. Is there any benefit to doing it in one step ?

    Thanks for any help !
