Hello Raymond and welcome to the Cow Audio Forum.
Provided the two track audio isn’t stereo or split track, you can ignore or turn down one channel of it.
If Premiere allows it, you can also just delete the second track.
That won’t necessarily improve your chances of “blending” the audio, but it’ll make the tracks easier to deal with.
There’s an art and craft to movie sound that doesn’t have anything to do with track count. Crossfades are your friends. In addition, you may (or may not) want the audio from the next scene to start early to pull you into the scene change.
Regards,
Ty Ford
