Moreover, this value leaves some room for other effects you might want to apply. 1.0 dB is optimal because going beyond this value may distort your audio and make it hard to listen to. The second option given by Audacity is to Normalize peak amplitude to any value you like (as you’ve already adjusted the DC offset, you can proceed to normalize the amplitude between peaks). Just check this box to avoid offset before you edit the track (the DC offset can block some other editing options, so it’s best to do it before you apply any of the effects). The DC offset can distort the audio, so it’s essential to make sure that the waveform is on the 0.0 line. This might look complicated, but it isn’t. The first option is to Remove DC offset (center on 0.0 vertically).

The first allows you to edit the sound in a movie and not just a stand-alone audio track, and the latter offers a large number of effects.

Using the Normalize option is really no different from turning up the volume control.īelow, we’ll describe how to handle the two best MP3 normalizers, Movavi Video Editor Plus and Audacity. Because the same amount of gain is applied throughout the whole audio track, the signal-to-noise ratio and relative dynamics rest unchanged. Applying the Peak Normalization effect increases the dB level across an entire audio track by a constant amount. Peak Normalization, on the other hand, is the process of making sure that the loudest parts of an audio track don’t exceed a specific dB value. 14 LUFS is also the standard normalization level for many other streaming platforms. Here are the loudness normalization levels that music producers usually stick to. Loudness Normalization helps ensure that the average volume of your audio is the same from track to track. So Loudness Normalization simply refers to the process of attaining an average value. LUFS are used to measure the loudness over the entire length of an audio track (average value).

The first is Loudness Normalization (more accurately, LUFS, Loudness Units relative to Full Scale), and the second is Peak Normalization. Sometimes you can edit an MP3’s volume using automation, clip gain, or a plug-in.īut what does it mean to normalize audio? Precisely what does Normalize do? In fact, there exist two kinds of normalization. There are situations where it’s best to abstain from using it simply because there are better ways to get the same result. Of course, the Normalize effect should be used wisely.

In fact, this used to be the problem about three decades ago, due to the processing algorithms. Some of them claim that normalization can degrade/change dramatically the way the audio sounds. There’s a myth about audio normalization that beginners bring up when they come across this topic. Another purpose is matching volumes in a series of audio tracks recorded at different volumes (often the problem with podcasts episodes).

But why and when would you need to normalize your audio?įirst of all, to get the maximum volume for a quiet audio file without changing the dynamic range (for example, tweak the audio in a movie with a low sound level). One team claims that normalizing your audio can degrade it the other group says sound normalization can be a handy tool. The Audio Normalization effect has been around since the beginning of digital audio, but opinions in the music society are still contradictory.
