Imagine you have a toy car and a toy truck. Both toys make noise when you play with them, but the truck is louder than the car.
Now imagine you have a tool that can help you measure how loud each toy is. This tool is called a meter. The meter can tell you how many units of sound each toy makes.
But, different toys make different types of sounds. Some sound higher, like a whistle, while others sound lower, like a drum.
So the people who make movies and TV shows created a special meter that measures a specific type of sound that is important for making sure everyone can hear what is being said. This meter is called an LKFS meter.
LKFS stands for "Loudness, K-weighted, relative to full scale."
This means that the LKFS meter measures sound loudness, but takes into account that different types of sounds can sound louder or quieter to our ears.
For example, if someone is speaking on a TV show and the background music is very loud, it might be hard to hear what they are saying. The LKFS meter can help make sure the overall sound is balanced and the dialogue is audible, while still letting the music play in the background.
So, LKFS is a special tool that helps make sure everything sounds just right on TV shows and movies.
