To me, normalization is just an automatic way of turning up the master volume. It does it in such a way that it knows exactly where to go. The signal to noise ratio is always going to be the same at this stage, no matter how loud the 2 track master is.
So, in a way Zeppe, you're right. It will turn up the noise.
However, it will also turn up the signal, and sound the same.
If somebody were to listen to the song, and it was a few dB quieter because it wasn't normalised, they'd probably turn up their speakers. Same thing isn't it?
If anything, compression and limiting is worse for noise than normalization.
Let's say you have a track, and the noise is about 30/40 dB below the average signal level, all the time. If you normalize it to 0dBFS, it will still be 30/40dB below the average signal level, all the time.
If you limit the recording and get roughly 10dB of gain reduction and then turn up your make up gain by 10dB, the noise will increase by 10dB when there is no signal.
Beat me to some of that.
If the overall signal is increased , then the fact that the noise floor increases has no real effect. The ratio or proportion of noise to desired signal is exactly the same.
