Since normalization is a constant gain change, it works the same way as many other types of level adjustments.īefore you reach for the normalize function, make sure there isn’t another method better suited to the job. Modern DAWs have many different options for changing the level of audio signals. If you do this and discard the original, you’re stuck with the normalized version!īefore you reach for the normalize function, make sure there isn’t another method better suited to the job. Audio normalization sometimes requires you to create a new version of the file with the gain change applied. Unfortunately there are some operations in the digital domain that are still technically destructive.Īny time you create a new audio file, you commit to the changes you make. But in your DAW you could simply drag the corners of the region out to restore the file. What does that mean? Think of a strip of reel-to-reel tape-to perform an edit you need to physically slice it with a razor!Īfter that you can’t just go back to the original. Normalization is often destructiveĭigital audio workstations, or DAWs, revolutionized music production with their non-destructive workflow. Normalization might seem like a convenient way to bring tracks up to a good volume, but there are several reasons why other methods are a better choice. It might seem like a convenient way to bring tracks up to a good volume, but there are several reasons why other methods are a better choice. Normalization isn’t commonly used in many music production situations outside of sampling. You can use your sampler’s normalize function where needed as you build patches and presets. It’s handy in this situation because the dynamic range and signal-to-noise ratio remain the same as they were before. Normalization is still a common feature on hardware samplers that helps equalize the volume of different samples in the memory. Normalizing audio helped get the best results from primitive AD/DA converters. In the early days of digital audio many components had limited performance when it came to dynamic range and signal-to-noise ratio. With all the less invasive ways to increase a track’s gain out there, why would you need to know how to normalize audio? When to use audio normalizationĪudio normalization is a bit old fashioned by modern standards. This averages the peaks of an audio file and adjusts the volume to that average. It creates the most natural and consistent results.Ī common method of loudness normalization is RMS volume normalization. Loudness normalization takes into account the frequency content of the audio, adjusting the volume based on the perceived loudness. You can use this to make the volume as loud as possible, but it doesn’t consider what the final track will sound like to the human ear. Peak normalization looks at the highest peak in the audio file and adjusts all of the audio based on that peak. There are two types of audio normalization: Normalization is typically used to scale the level of track or file to just within its available maximum. If that sounds complicated, all it means is that audio normalization brings up the volume of a file to the maximum amount based on the loudest point. Normalization applies the same level increase to the entire duration of an audio file. What is audio normalization?Īudio normalization is a process that increases the level of a recording by a constant amount so that it reaches a target-or norm. It’s not always easy to tell whether to apply normalization or to avoid it completely-and getting it wrong can cause issues in your mix.īut what does audio normalization do? And how does it work? In this article I’ll break down what audio normalization is, when to use it and when to steer clear. It’s a music production process that’s been around since the earliest days of digital audio, but is it still relevant? Audio normalization is a concept that comes up fairly often for new producers.
