\u30fb Is the volume of the sound source uploaded to the video site lower than that of the original sound source?
\n\u30fb The sound source and volume of the CD are completely different from those of Youtube.
\n\u30fb Sound pressure and volume increase with MIX, but it sounds small for some reason.
\nHave you ever felt like this when you were singing or posting on YouTube?
\nThis is all because a feature called loudness normalization is working.<\/p>\n
It has recently been introduced to Nico Nico Douga and applied to most music streaming services (subscriptions, etc.) in recent years.
\nLet’s briefly explain what happens to loudness normalization and what to do in the future.<\/p>\n

\n4 Summary<\/p>\n
What is loudness normalization?
\nIn conclusion, loudness normalization is a
\nA specification that automatically reduces the sound when the volume exceeds a certain value.<\/p>\n
It can be misinterpreted, but it is not a specification that reduces sound pressure.<\/p>\n
Loud sounds are louder and cooler than listening to soft-sounding music!
\nI think there are a lot of people who say that.
\nHowever, if I personally think about why I voluntarily decided to lower the volume, I would like to increase the credit.<\/p>\n
merit
\n\u30fb Eliminate variation in the sound of each song \u30fb
\nNo need to adjust the volume every time you watch videos continuously
\n\u30fb As a result, your ears do not get tired
\nThe above can be mentioned.
\nAll songs have a constant volume, so even
\nIf you play music or videos continuously, you can avoid the problem of “the volume suddenly increased when the next song came!”.<\/p>\n
You don’t need to turn down the volume, and it seems to be just a merit, but from a musical point of view, there are a few issues to consider.<\/p>\n
A mix with “margin” is important
\nI’m sure there are people who say, “If you can turn it down without permission, no problem with high volume and sound pressure!”
\nAnyway, it’s great! I have prepared a simple diagram of what happens to the sound source mixed with loudness normalization.<\/p>\n
As you know, if you increase the sound pressure too much by mastering, the waveform will become a sound source that will fill with sound and get louder.<\/p>\n
If the volume is forcibly reduced by normalizing the loudness in the state of a sound source with lost dynamics, the lack of power can be highlighted and heard.<\/p>\n","protected":false},"excerpt":{"rendered":"
