Also, should I always be recording in mono? I thought stereo was better, but I’m honestly not sure why.
You can do whichever you want. The quality of performance does not change.
But there may be other considerations.
I record in stereo and present stereo sound files to the video editors on the third floor because I know that’s the form that will match the rest of their work. I effortlessly become one of the stereo sound files in their production.
One of my larger voice recording setups naturally produces stereo and I would have to go to extra effort to record or create mono. So I leave it stereo.
I have a different audio setup that “likes” mono, so that one I leave mono.
Recording using the laptop built-in microphone can be done either way, so I usually do that mono.
Stereo files take twice the drive storage that mono files do.
If you’re posting to ACX AudioBook, they strongly recommend submitting in mono. They also strongly recommend your whole book match.
Effects, production, filtering, and other processes are faster in mono.
If your goal is to integrate your voice into a stereo show, my personal preference is do everything in stereo including the voice. I don’t like automatic adaptation that happens in the background.
Please note that shooting the voice in actual stereo with two microphones is strongly discouraged. Any movement in the presenter’s head will give a swishing, weaving effect in the track and make production very difficult. Even in movies with seven surround tracks, etc, the dialog is almost always mono and carried in the single center track.
And there is even a variation on that. Live conferences, meetings and production screenings, work better in two microphone stereo. Anybody listening to the conference later on headphones can easily pick out different participant voices even speaking at the same time.
Aren’t you glad you asked?
