Normalize audio, then reduce the volume in ffmpeg
27 octobre 2014, par Steve SheldonI 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 :
- Is there a way to do this in one step ?
- Is there any benefit to doing it in one step ?
Thanks for any help !

In cases where the execution inside the function execute_model_ov fails,
push the RequestItem back to the request_queue before returning the error.
