3. First, we'll set the threshold, which will expand any audio signal above this level. On the Expander's in-
terface, drag the Threshold slider all the way to the bottom so that it reads -50 dB. Next, we'll set the relat-
ive amount of expansion when the signal exceeds the threshold level. Play back Scene 17 Slate 31 Take 2
and experiment with the Ratio slider on the Expander's interface. Drag the Ratio slider all the way to the
left so that it reads 0.5 (see Figure 13.8).
As you play back Scene 17 Slate 31 Take 2, turn the Channel EQ and Expander plug-ins on and off in the In-
spector to hear how we've much improved the audio on this clip. The background noise hasn't been completely
removed, but we've taken away enough of it to make the clip usable. Adding background room tone and music
also will help conceal whatever noise is left. The rest of the clips in this sequence also suffer from varying de-
grees of background noise, which would need to be removed using the same procedures. However, rather than
have you go through the pain of doing this for every clip in the project, we've had the original camera audio
professionally processed by the movie's dubbing mixer, Ken McDowell. This has been provided as a single
Dialogue audio stem, which we will be using to build the rest of the soundtrack later in this chapter.
