I record a lot of tutorial videos for my work. I don't use background music or sound effects, just a voice over a screen recording.
One thing I have noticed is each of my videos (so far) has a different overall volume. If people were to listen to the videos in succession, they would be constantly adjusting the volume level. I want to normalize the audio so that it is all at the same level.
My problem is I can't seem to find a standard anywhere for a general decibel level to normalize all my videos to. Is there an ideal audio level that plays at exactly the level a typical viewer would expect for their volume setting?
In other words, if a viewer was just watching, say, a professionally made movie, and then watched my video, ideally they should not have to adjust the audio setting on their computer when switching to my video.
