Since full-on construction isn’t exactly inexpensive, let’s focus on picking the best room you already have access to.Ĭhoose somewhere remote, preferably without windows. To block noise from entering a room, you need thick walls made out of a dense material.

You’ll also want to use a professional microphone to pick up the best audio possible (Check out this blog about picking a microphone if you need help). But don’t worry yet, there are a few tricks you can use to get around this setback! Things to tryįor a truly masterful voice over, you’ll want to control for everything we’ve covered above: blocking outside noise, absorbing stray sound waves, and diffusing the rest. Usually soundproofing is taken care of during construction because it can be difficult to reinforce a room after it’s finished. Generally, very dense materials are good at this. To soundproof, you have to stop sound waves from entering a room. To get the best overall audio, use absorption and diffusion together.īlocking external noise from entering a room Diffusion is just another word for scattering sending reflected waves in different directions has a smoothing effect. Absorbing all the errant sound waves may seem like a good a idea, but if you absorb too much, your recording will start to feel unnatural or lifeless. Absorbing sound waves reduce the strength of the reflection. To fix this problem, we have two options: absorb the reflected waves or diffuse them. Because reflected sound arrives at our ears later, it causes distortion. On the flip side, reflected sound is created by sound waves bouncing off walls. Direct sound comes from sound waves going directly to your ears (or voice recorder). Like John says in the video, there are two types of sound in a room: direct and reflected. To give you a better visual of what this means, I’m going to turn it over to John Calder of Acoustic Geometry. As you might imagine, sound bouncing back and forth across a room doesn’t make for the highest quality audio. If you’re in a room with more than one wall (and let’s be honest, that’s most rooms), the sound wave will bounce back and forth. When those waves hit something (like a wall), they bounce back. Once we understand what makes a voice recording echo-y or scratchy, we can start fixing the problem.

I can think of a few excellent videos that don’t have any speaking parts at all! But for anything with a voice over, on-screen dialog, or interview, you’ll want to make sure the sound quality is as good as possible.īefore we talk about how to soundproof your own room, let’s take a quick look at how sound works in the first place. Of course, some types of videos are less driven by audio than others. Your point gets lost in the static along with your voice.
No amount of set design, camera effects, or lighting tricks will help your finished video if your audio sounds like an old cassette tape.īeyond seeming unprofessional, poor audio quality makes it difficult for your viewers to understand the video. Nothing kills a video like poor audio quality.
