What are the correct audio levels for video? You can also turn this feature off if you feel confident that you got what you wanted during the audio mixing process! Just know that many platforms will perform automatic audio normalization when they start playback of your content, so it’s worth it to make sure you’re within their range before you send it off to them. In Descript, we have several ways to normalize audio: you can set the program to cut off at certain peaks, or ask it to push toward a certain pre-set loudness level. Many video editing programs include an opportunity for a final tweak as you export your video file. Did boosting a certain frequency add loudness that you now need to reduce? Did cutting a different one make someone’s voice too quiet to hear all of a sudden? You'll still be measuring levels in dB here, but you'll also want a loudness monitor that's measuring in Loudness Units Full Scale (LUFS) while you're mixing. It’s also especially important to pay attention to levels as you equalize your tracks. Mixingīut paying attention to levels doesn’t end there! Because again when you’re mixing, what you hear coming out of your speakers isn’t necessarily the true loudness level of your audio clips. You want your decibels measuring in the negative - 0dB is usually considered the absolute limit. During audio recording, audio levels are typically measured in decibels, or dB. This is basically what we mentioned above - checking to make sure that the loudness of what you’re laying down is in the right range for a) human ears and b) your publishing platform of choice. When you’re recording for video production, you’ll ultimately end up dealing with three sets of levels. Here’s everything you need to know about leveling for video. And while there’s nothing wrong with compressing - almost everything you hear has been compressed once or twice - having to do it too often or too aggressively can really flatten your sound. It can also alert you that you’re recording way too much noise, which will then have to be normalized and compressed as you edit. Leveling tells you what the machines are hearing - and lets you know that you’ll have enough information to work with when you get to post-production. It might seem like it could be replaced by listening, but the human ear is fallible, and changes based on the person (and the volume of their headphones). ![]() Leveling is important for a number of reasons. ![]() What the engineer is checking for is pretty basic: how much of your voice that mic is picking up, because your volume level in the room may not be the same as what’s being recorded. Well, they’re not that mysterious, actually. Something you’ve probably heard if you’ve spent time on sets is the phrase “checking levels.” A sound guy comes over, adjusts your mic, and has you talk about something - often what you had for breakfast, they love to hear about breakfast - while he looks at a monitor for mysterious signals.
