After averaging the volume, you can reduce unnecessary volume and focus more on sound quality. TV stations, radio and online music streaming platforms will play the volume for processing, which can avoid the phenomenon of turning up the volume to attract attention, which is what we call volume competition. The average volume of the overall sound is calculated and then the average volume is calculated and the difference between the volume and the desired volume can be adjusted. What is LUFS? It is short for loudness units relative to full scale, which is the unit used in EBU R128, and EBU R128 is a set of guidelines for standardizing loudness and the maximum allowable audio signal level.
Starting in 2015, they turned down the volume on music videos relatively loudly to avoid freaking out about the volume when switching videos, resulting in a bad experience., Set the volume to a low level and reproduce almost the same volume, the overall loudness value set is about -13 LUFS. The way YouTube regulates volume at first didn’t use -14 LUFS, which is an exact value. YouTube quietly adjusted its playback volume to -14 LUFS, achieving full equalization.
YouTube quietly changed its loudness playback policy to achieve full average
