As the comments are linked to the slides, you can adjust the position of the
slides and the comments will move with them. Remember that any unlinked
audio clips to the right of the one that moves will also move. The position of the
comment with respect to the slide can be adjusted by dragging the audio clip.
When you are happy with timing, add the background music to Track 2.
Either use volume envelope to lower the background music during the
comments or lower the volume of the whole track so it does not overpower the
commentary as described in 'dynamic range reduction'
Figure 4 shows the final result for the first two slides.
Advanced features
A few of the more advanced audio features of PTE are covered briefly
below. You will probably discover others for yourself.
The colours used for the graphical display of audio clips on the timeline can
be customised. Select Preferences and then the Timeline tab and look at the
section called 'Color of audio clip'. One useful change is to make the colour of
a selected wave a slightly darker shade of green.
Tracks can be locked by right-clicking the track in the timeline view and
selecting 'Lock Track'. Audio clips in locked tracks cannot be moved. However
if they are linked to a slide they will move if the slide is moved.
On the Audio tab of Project Options at the bottom right is an option 'Convert
tracks to mp3 for exe'. If this is checked, all audio files will be incorporated in
the exe file as a single mp3 format file, irrespective of the original format. This
keeps the size of the exe file down if you have included any wav files in the
sequence.
When dragging audio keypoints on the timeline, the volume indication can be
shown in dB rather than %. The choice is made in the 'Sound volume' combo
box on the Timeline tab of Preferences.
