How to lower the volume of the second audio channel with FFMPEG

Question

It's easy to mute one of the audio channels of a video, but I have to lower the second one with some dB.

I have searched in documentation about mapping the channels but I am still confised how to lower the volume of the specific channel. I have only two audio channels in my videos.

Thank you for the help!

After a few hours of searching, I was only able to find this.

I don't know if that's kind of what you are looking for, or at least gives you the info you need to modify the channel volume.

I hope it helps!
