How to match tracks in Adobe Audition?

Question

Adobe

Hello. I recorded a conversation in Skype, after recording it turned out that the interlocutor's voice was heard in one earphone and my voice in the other. I opened the audio recording in Adobe Audition and the question actually arose, how to combine these two parts into one?
The goal is to make sure that the sound is played simultaneously in both headphones.

Answer 1

stereo -> mono
