![]() This is illustrated by the following diagram, which represents the 3 components in a typical voice-over soundtrack. So every time you pronounce those consonants for example, you are at risk of introducing audio saturation. And some specific voice sounds – such as plosive consonants (‘p’, ‘t’) – introduce very rapid peaks in audio levels. It is very difficult to speak with a constant volume: sometimes you speak louder, sometimes softer, even within the same sentence (ordinarily people tend to end sentences with a softer tone). The human voice has wide audio dynamics.As a general rule, you must avoid hard clipping at all times. If your overall volume exceeds that limit, what then happens is called hard clipping: the audio sounds distorted, saturated. In digital audio there is a maximum loudness threshold that you are not allowed to exceed.The issue you are facing here is two-fold: For example, if at one point in time there is a loud noise in the ambient sound, it may cover the music or the commentary (which you don’t hear clearly anymore). These 3 components fight each other for a share of the overall audio volume. The video soundtrack as was initially recorded by your camcorder (e.g.When adding a voice-over, your video typically ends up having 3 distinct audio components: It does not need to be complex however: with a free software tool and no more additional work than a simple drag-and-drop, here is a practical tutorial to help you reach fantastic quality in your voice-overs.Īny question or comment on this article?

To overcome this issue, you need to understand and take advantage of one essential audio production technique: dynamic range compression. But recording voice is more difficult than it may seem: sometimes it is too loud, and sometimes instead you can’t hear it well.
