I usually set background audio elements to an average of -22dB (or so) and foreground elements to an average of -12dB with nothing peaking above -6dB. To adjust this gain, I select the clips first and then press G to open a dialog that I use to adjust my clips. What I do is select all of my foreground audio (voice-over or dialogue) and adjust the gain of all of these clips at the same time, and then select the background audio (music and Foleys) and do the same. Use this value as a guide, not as a setting suggestion (a good reference level for broadcast is -12dB with a dynamic range of 6dB). However, this will give you a peak value that is way too loud. If the Peak Amplitude value is -12dB, theoretically you can add 12dB of gain. It displays the peak amplitude in a clip before gain has been applied. Keep an eye on the Peak Amplitude measurement at the bottom of the Audio Gain window. Music, for example, usually comes in too loud, so it will definitely save you time if these elements are already at a better level before you add the clip to the Timeline. Most of the audio that you will get in your project will come in at a level that is not ideal. This is easy to do, and it will save you time. Adjusting Gain in the Project Panelīefore you add clips to the Timeline, you should start doing some pre-mixing. Unless there is a really good reason for not doing so, our audio levels should be even throughout our program. Sometimes audio levels are used to produce an emotional response. Most viewers (listeners) will expect some kind of evenness of the audio levels in the program. You should not have a portion of your program be disproportionally louder than the rest it will cause confusion to the viewer and your message will not be as clear to them. Why should we worry about the loudness of the clips matching? Because it is important to establish audio continuity in your work. Figure 4.4 Audio levels after being normalized to -12dB.
