Sound volume by track at run time

[aplman]

Sometimes in my travel presentations, I wish I could reduce the volume of the background music, to anable my hard-of-hearing audience members to concentrate on my carefully produced mellifluous narration.

I appreciate the many advantages offered by exe shows.  To be able to adjust volume by track while showing would be another important step ahaed of the competition.

Hello aplman, It would be wiser to mix it correctly once when you create your project.
As the message véhiculated by your voice is far more important than the background music, why not mix them consequently?

Some multimedia editors support audio ducking. I think it has been requested before but I have not verified.

Audio ducking can only respond to what has happened & reduces the audio following to whatever level you select.
However this works when editing a track.

As mentioned above set your sound levels to the correct volume in the first place.

Music should be at least 20db below the voice level to be clearly heard.
