I'm still experiencing the same difficulty. A couple of
further thoughts:
First, I realize now that the waveform in Presenter 6
represented mono sound, whereas the waveform(s) in Presenter 7 are
stereo. I don't know what, if any, impact this may have.
Second, I may be able to work around the "clicks" and "pops"
that occur at the transitions to and from "silence" if I can find
some way to insert white noise (at the same amplitude as the
background noise) instead of inserting silence. I suspect that I'll
have to copy and paste the white noise from elsewhere in the audio
track.
Any thoughts? This is very frustrating to me since I was able
to get very professional sound from Presenter 6 and the transition
to Presenter 7 has been a step backward with respect to audio
quality.
Thanks,
Paul
