I do not know if I understand right, you set the audio volume in AudioDirector or WavEditor and then produce saved the video without the audio setting?
Talves you saved by not updating the audio in PD.
Certain adjustments will be better can do so directly in PD will see the positions in video can help in some cases.
This is done directly in the wave of audio, acting on the white line, click the line hold and drag down and up.
To better visualize the wave expand it, click on the bottom line, an arrow appears drag down, increases the height of the wave.
