Why every audio part louder in FFmpeg while I join them in one audio ?
13 mai 2024, par Volodymyr BilovusI trying to make dubbing for audio. I have original audio track and I want to put translated audio parts on top of the original.


translated audio 100% vol : —p1--- ---p2— -----p3--- —p4—


original audio 5% vol : -----------------------------------------


Here is my FFmpeg command with filter_complex


ffmpeg -i video_wpmXlZF4XiE.opus -i 989-audio.mp3 -i 989-audio.mp3 -i 989-audio.mp3 -i 989-audio.mp3 \
-filter_complex "\
[0:a]loudnorm=I=-14:TP=-2:LRA=7, volume=0.05[original]; \
[1:a]loudnorm=I=-14:TP=-2:LRA=7, adelay=5000|5000, volume=1.0[sent1]; \
[2:a]loudnorm=I=-14:TP=-2:LRA=7, adelay=10000|10000, volume=1.0[sent2]; \
[3:a]loudnorm=I=-14:TP=-2:LRA=7, adelay=20000|20000, volume=1.0[sent3]; \
[4:a]loudnorm=I=-14:TP=-2:LRA=7, adelay=30000|30000, volume=1.0[sent4]; \
[original][sent1][sent2][sent3][sent4]amix=inputs=5:duration=longest[out]" \
-map "[out]" output.mp3



Audios I put on top of the original audio track is the same
-i 989-audio.mp3
I made it by purpose to show the problem
And here is the audio levels on final generated track.


As you can see, first and second only slightly different but third
and fourth have totally different(higher) volume level (Notice, audio is the same).
Why it's happened. And how can I workaround this odd behaviour ?
