![]() You can look over this presets walkthrough to get more familiar with the options! More Audacity tutorials The Manage dropdown menu lets you adjust the Normalize tool presets, which are useful if you want to save settings that you frequently use and access them quickly later on. If you like what you hear, you can click the OK button to apply the normalize effect to the selected audio. Helpful features & buttonsīefore you apply a change to a stereo track, you can use the Preview button to listen to six seconds of the audio and before you make any final decisions. If you aren't mixing two microphones, you can leave this box unchecked. If that's the case, select the checkbox to normalize stereo channels independently and adjust the amplitude separately for each channel. You'd want to analyze both of these channels separately because you might be speaking in a different volume than your co-host or your guest throughout the dialog. Let's say you're using a Behringer mixer and mixing two microphones - one's recorded on the left side of the stereo mix, and one on the right side. The most significant difference is that Normalizing helps remove the audio disparity between tracks, while amplification changes the volume level one or more tracks by the same amount. Note: Amplify and Normalize are similar effects that can easily get confused. If you select multiple tracks and adjust the peak amplitude, the changes will apply across all selected audio. To normalize lower amplitudes, enter a more negative value (like -2 dB.) The level of -1 is purposefully just below maximum amplitude to leave a little headroom for effects and quality playback. Extending past this boundary results in distortion and clipping, and even though you'll be able to hear the audio without a problem, it won't sound very good. ![]() This value is important because you don't want your track's loudest parts to be so loud that they extend beyond -1 dB. But keep in mind, it's important not to adjust amplitude before correcting DC offset! If you've already corrected your DC offset, you can move onto normalizing the amplitude between tracks. The second option is to normalize your peak amplitude to -1 dB - or whatever value you want. Pro tip: Because DC offset can throw off other aspects of editing, we suggest doing this step before applying amplitude to the track. This detailed walkthrough can help you enable the setting in your version of Windows. Some new PCs might have a DC offset cancellation feature when you record from the device's built-in inputs. Checking this box is all you have to do to avoid offset. If you go back to your track, you'll see the 0.0 mark, and you always want that to be in the middle. If the DC offset isn't on 0.0, it can distort your audio and not leave enough space for other effects. The first option it gives you is to Remove DC offset and center on 0.0 vertically (don't worry, this isn't as complicated as it sounds.) Moving the DC just means making sure your waveform is on the 0.0 line. In this menu, Audacity will give you a couple of options. You can also select multiple tracks and normalize them all at the same peak level.įrom there, go up to the Effect tab on the top of your screen and click Normalize. ![]() You'll notice the track's color change in the background, so you know you've selected the entire thing. You can press Cmd + A or Control + A to select the track. So here we have a track we imported into the workspace. Now that you understand the situations in which you'd need to normalize your audio, let's look at the different normalization components and how to add the effect within Audacity. If the volume is too low, you might not even see the waveforms or hear the content, making editing pretty close to impossible. Amplifying your audio quickly fixes all these problems! The other reason you would normalize audio is that your audio recording isn't loud enough. The last thing you want is to record a voiceover that's way louder than the clip that comes after it, or vice versa. You can use the Normalize tool to make sure one is not too loud or soft. Let's say you have an intro music segment, a narrated segment, and an interview section you want to all be at the same volume level. To match the volume levels across different clips There are two main reasons you'd want to normalize your audio files, and both situations arise in nearly every podcast edit. When do you need to normalize your audio?
