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.

    This is too vague to be an answer, so I'm posting it as a comment. In many video (and most audio) programs, you can see a graphic "audio level" monitor that shows green when the volume is good, yellow when it is too loud, and red when it is way too loud. If you can keep your voice over so it is always near the top of the green, with just a few yellow spikes, the volume level will be pretty typical. Commented Feb 5, 2015 at 0:27

    ^in my experience with FCPX, the waveform cannot be trusted. When you see red peaks, it can mean either 0 db or -6 db. Commented Feb 5, 2015 at 17:16
  • "Normalise" (or normalize) is exactly what you need to do. Unless your video is going to broadcast TV you can safely normalise your levels to 0dB using whatever normalisation effect your sound editor has. Do this as the last step before exporting.

There's no single answer - it's a series of trade-offs:

When you record your voice, it should be as loud as possible, but making sure never to go over the maximum level that can be recorded. This is known as clipping, and sounds distorted. Too quiet, and your audio will be hissy relative to the noise floor of your setup - too loud and it will clip.

In order to smooth out the overall levels, you can dynamically compress your audio (this is not the same as data compression), either before it is recorded (between the mic and recorder) or after it has been recorded. This is effectively like having an automatic volume control, where levels over a certain threshold are turned down, so that the overall effect is smoother. Too much compression can sound pumping and aggressive - like an FM talk-radio host.
