What Does Audio Normalization Do and How to Use It

Imagine watching your favorite YouTube video or listening to a podcast. Suddenly, loud spikes in volume jolt you. Or, you strain to hear the quiet dialogue. These uneven audio levels can ruin the experience, whether you're casually listening or working on a professional project. The problem is common, but the solution is simple: audio normalization.

Audio normalization is a powerful tool that ensures consistent sound levels across your music, podcasts, videos, or audio content. It enhances the experience and makes your content sound professional. If you're a content creator or an audio fan, know this. It's crucial to understand audio normalization. You must know how it works and when to use it.

Key Takeaways of What Audio Normalization Does

Audio normalization adjusts the overall volume of an audio file to ensure consistent levels. This feature analyzes the peaks or loudness of the audio and aligns them within a specific range. So, if you are a podcast fan or YouTube viewer, you can enjoy a seamless experience. Here is the audio normalization benefits you need to know:

• A smoother and more enjoyable listening experience
• Professional-grade audio for podcasts, videos, music, and other media

Types of Audio Normalization

• Loudness normalization adjusts audio levels to match how humans perceive loudness. It measures loudness over time, not just a moment's volume. It uses standards like LUFS (Loudness Units Full Scale) to ensure a consistent, natural listening experience.
• Peak normalization adjusts audio levels by targeting the track's highest peak. It ensures the loudest moment reaches a specified level. This process doesn't change the overall loudness or perceived volume of the entire audio file, focusing only on the peak amplitude.

When to use Audio Normalization

Audio normalization has countless uses. It applies to podcast production, video editing, and live streaming. However, it's not always the right tool, especially in scenarios where dynamic range is critical. Stay tuned as we explore how to use audio normalization effectively, and the best software you might want to try.

How to Use Audio Normalization in Filmora

Step1After opening Filmora, import the audio or video file and add it to the timeline.

Step2Select the video or audio clip and navigate to Audio > Adjust Audio to open the Audio Editing panel. Turn on the Auto Normalization toggle.

After that, Filmora will automatically analyze and adjust the volume of the clip(s) for normalization.

If you're unsatisfied with the normalized volume, you can click the button again to reset it or use the recheck icon to adjust it further.

Problems with Audio Normalization and How to Fix

Even though audio normalization is a powerful tool, it doesn't mean it's without issues. Understanding these common issues and how to fix them can help you maintain the best audio quality for your projects.

Audio Normalization Isn't Working

Sometimes, audio normalization may not work. The volume levels may be unchanged or inconsistent.

Solution:

1. Check Audio Format: Ensure that your audio file is in a format that supports normalization, like WAV or MP3. Some compressed formats may not work as effectively.
2. Verify Settings: Double-check that the Auto Normalization option is enabled in the Audio Editing panel.
3. Manual Adjustments:If automatic normalization fails, you can adjust the audio levels manually. Use the volume sliders in the Audio Editing panel.

Loss of Dynamic Range

Normalizing audio can sometimes reduce its dynamic range. This can make the audio sound flat and less expressive. This can happen if the normalization process is too harsh or applied incorrectly.

Solution:

1. Use Subtle Normalization: For music, avoid maximizing the audio to a target level. It can ruin the dynamic range. Use a more conservative approach instead.
2. Manual Volume Adjustments: If the auto normalization limits the dynamic range too much, you can manually adjust specific sections' volumes to preserve natural variations.
3. Try Peak Normalization: Instead of loudness normalization, use peak normalization. It makes less intrusive volume adjustments.

Over-Normalization Leading to Distortion

Over-normalization may occur if the volume is turned up too high. This may cause distortion or clipping, especially at the loudest moments of the track.

Solution:

1. Avoid Over-Normalizing: Don't push the audio too close to 0 dB. It may cause clipping.
2. Use Compression: To balance the sound without over-normalizing, consider using compression in addition to normalization. Compression lowers the loudest parts and increases the quietest parts. This keeps the sound balanced without distortion.
3. Limit the Target Level: Set a target level that leaves some headroom to ensure that the audio does not peak and cause distortion.

Conclusion

Audio normalization becomes essential if you want to create enhanced and prol-sounding content. Adjusting the volume for consistent sound improves the listening experience. This applies to podcasts, videos, music, and live streams. Filmora provides an easy way to normalize audio. It helps adjust audio levels without losing quality. Audio normalization tools also have potential issues such as over-normalization or loss of dynamic range. You need to take steps to overcome them to get the best results. With the right approach, audio normalization can improve your projects.

Regardless of your skill level, understanding how to use audio normalization effectively will ensure your content sounds balanced, clear, and enjoyable for your audience.
