Let the Arrows Guide You

The two arrows in the Program Loudness section indicate in which direction you should go - and to which degree.

If both arrows are green as in the example to the right, you are good to go.

Your Program Loudness level is within target, and no further adjustments are necessary.

If the upper arrow is yellow, your material is too loud and you should decrease the volume to hit the target. 

If the upper arrow is red, your track is much too loud, and you should lower the volume drastically.

If the lower arrow is yellow, your material is too soft and you should increase the volume to hit the target. 

If the lower arrow is red, your track is much too soft, and you should raise the volume drastically.
