![]() ![]() If this is starting to feel complex, don’t worry, here’s the recommended settings for normalizing audio with loudnorm: $ ffmpeg -i input.mp3 -af loudnorm=I=-16:LRA=11:TP=-1.5 output.mp3 ![]() This normalization standard is called EBU R128 and what the loudnorm filter is built off of. This filter increases volume without changing the sound, compression or quality. Normalization with loudnorm, uses a true peak loudness to increase the maximum volume for each bit.įor audio signals on radio and tv broadcasts, a guideline exists for the permitted maximum levels thus setting a standard for increasing the volume throughout a track. Ever get an audio file that just isn’t loud enough but when the volume is edited it peaks? The solution for this problem is to run the audio through a normalization algorithm. ![]()
