I am using (1) Camtasia Studio 8.6.0, (2) Power Point 2010, and Audacity 2.1.2. These tools run under Windows 7 Pro, 64-bit, Service Pack 1.
I have a Camtasia Project w/ three tracks: (1) images (in separate files), (2) voice (in separate files), and (3) background music (in one file). There is no voice associated w/ some of the images.
I raised the volume of the entire voice track and I lowered the volume of the entire background music track to 33%.
I now want to raise the volume of the background music track to 50% but only where there are images w/ no voice associated w/ the images.
How do I do it?
