Keep in mind that the sound of your voice bounces off hard surfaces like windows and tiles-which you want to avoid. The most obvious way to eliminate noise from your recordings is by finding a quiet space away from potential interruptions, ambient sounds, and background noise. Record in the quietest environment possible Here are five things you can do to capture clean audio. Before recordingīut while Studio Sound can work wonders, you should still be doing everything you can to get the best possible audio when you record.

With one click, it removes background noise, reverb, plus other sounds you don’t want, and enhances your voice, so it sounds like you recorded in a studio. Descript’s Studio Sound is a good example. Otherwise you were screwed.īut these days, artificial intelligence (AI) and machine learning are making it easier to fix bad audio when you’re editing, even if you’re not a pro.

So if you weren’t a sound engineer or a professional editor, you’d better have a good mic and a soundproof room. And even for the best sound engineers, trying to remove background noise was, as Prem puts it, like trying to remove sugar from a cake you already baked. There are two main ways to control the variables that affect the quality of your sound: (1) before recording, choose the right gear and create a good recording environment and (2) after recording, use an audio editing tool to remove remaining background noise in post-production.įor most of audio-storytelling history, post-production noise removal was something only the experts could do. Follow these steps and you should be fine. That actually makes it sound more complicated than it is. To achieve clean audio, and the superior listening experience that comes with it, you need a good speech-to-noise ratio: subtle room tone, and the right balance between clear direct speech and indirect background sounds. It sometimes sounds ‘smooth’, and other times more ‘crackly’, depending on the mic. This noise mostly comes from a current running in the circuitry. In fact most record with their built-in laptop mics, which tend to hear sound differently they don’t pick up low frequencies as effectively, and some may introduce mic noise-noise generated by the mic itself. But most creators don’t use professional grade mics. A high-quality mic responds to a range of frequencies, and stays mostly true to your room’s recording conditions. It’s the difference between how you sound in a closet, where clothing or carpeting dampens the sound, versus a parking garage, where sound reflects off the hard surfaces, causing echo. Indirect sound, on the other hand, is the residual sound left bouncing, or reverberating, around your recording environment. “That’s the sound that goes directly from my mouth to the microphone,” Prem says, pointing to his recording setup. When we talk we produce two kinds of sounds. “When you speak into a mic in any sort of room, there’s also this kind of noise that’s happening all around you,” Prem says. Professionals call it room tone-the sound of the room, or sound of silence. Every recording environment has a certain audio quality when no one or nothing is making sound.
My colleague Prem Seetharaman, an AI and audio researcher at Descript, breaks noise down into three categories, each with its own causes: Noise is a normal byproduct of sound recording, but when it consists of obvious, unwanted background sounds it can have a noticeable-even deleterious-effect on your recordings. In audio recording, noise refers to residual low level sounds, the ambient noises you sometimes hear during the quiet parts of a recording.
