Converting Stereo audio to mono is important when you are recording to stereo and only one of the two audio tracks is needed. Or when you have only recorded one audio source and there is no audio coming from one side of the speakers.
When recording audio with only one source, it is usually better to record in Mono, however, on the fly and moving quickly, sometimes you just don't have time to modify the settings. Good news! Adobe Premiere Pro CC provides a quick way to change the audio channel source.
After poking around at some of the common suggestions for fixing this issue, I was surprised at some of the lengthy and time-consuming ways people recommended fixing the Stereo to Mono issue. This method is far quicker than most.
