We can correct this fault by using the Normalize effect with "Remove any DC offset" selected. In Figure 1 you can see that the upper track is not centerd on the horizontal line, but above it. A minimal amount of offset is very common, but large amounts (such as in Figure 1 below) should not normally happen. If DC offset is present, you should always use DC offset correction. Using Normalize with DC offset correction

If the DC offset correction in Normalize is not applied, each of these methods will do exactly the same thing and the resulting audio will be identical. With a -6 dB track, Amplify will always default to the above "Amplification (dB)" and "New Peak Amplitude (dB)" values, because it always defaults to amplifying to 0.0 dB.

Set "New Peak Amplitude (dB)" to -0.0 dB.

"Normalize the maximum amplitude" to -0.0 dB.

If we have a track whose peak amplitude is -6 dB (+0.5 to -0.5 on the vertical scale), there are three ways to bring the peak up to 0 dB (+1.0 to -1.0 on the vertical scale). The slider can also be used to choose the amplification level without entering any text input.įor a single mono track, these are essentially different ways of saying the same thing. The Amplify effect offers two interdependent options (meaning that changing one changes the other): "Amplification (dB)", and "New Peak Amplitude (dB)". The Normalize effect offers the option to "Normalize maximum amplitude to" a chosen level.
