It seems that PowerDirector 11 "Audio Normalize" will try to match the volume of each of the selected audio clips to the clip with the lowest volume. After that, if you need to adjust the overall volume of a track, you can do that in the Audio Mixing Room (F9).
Audio Normalize will have the effect of compressing the dynamic range, which for the most part makes it easier to listen to on TV. You won't need to adjust the volume on the remote control constantly when going back and forth between the loudest parts and the quietest parts.
CORRECTION: Before using the mixing room to adjust the volume of a track, you need to save that audio track to a file if there are more than one audio clips on the track. When moving the mixing slider, only the clip with the timeline pointer over it is affected, while the other clips on the same track are unaffected. I guess I learned something new. I thought that all the clips on the track were affected. AudioDirector is probably what you need to handle numerous clips on a track at once.
