Excellent helped so much

Here is my view bro. According to the acoustic principle, every time the same frequency hits, the sound level will go up. (Imagine this, you have four channels, all playing the same track in the same level, like +9db, but you put all faders up, you definitely gonna hear much more louder than +9db with only one track.) So, let's say you stay track A just under the red, like +9db, no red, good. But no matter how you mix, once you mix in a track B, you will hit the red level actually (but you can't see red everywhere on the mixer, but your sound is distorting). Then, if you set track A to +6db when you mix track B with it, it probably just rises to +7db, +8db, no red in the end. At the last, the space between +6db is the 'headroom' that you need to save for the mixing and FXs. Peace.

Just because both songs are playing at -9dB DOESN'T mean they're equally loud! Loudness is not equal to peak dB. You must match loudness by ear as far as I understand.

when you use your trim is it suppose to show up on Serrano as well the same ?

Where can I find this song? The first track which looks like it's titled "Spend the Night Final Master Main"

Yellow is wrong like red. This is like a traffic lamp. Yellow is telling: turn down now! Nobody want to deaf. Thanks! Greetings from Netherland :) DJane

i need to know this for fusergame

The problem is that even if you adjust gain, when you start the second song with the same level's volume knob of first song, often the second song is or too loud or too light than first song. Why? And how could correct this?

How do you adjust records levels with a mixer without gain???
