How to Deliver Loudness-Correct Web Videos Without Being a Sound Engineer

You may have noticed that some web videos have inconsistent volume—one clip is barely audible, while the next is uncomfortably loud. Television faced a similar problem with commercials but solved it years ago with standardized loudness levels. Today, most web services have adopted similar loudness standards. While learning all the technical details might not be everyone’s priority, consistent audio is crucial for a professional experience.

At Voicemachine, we process all uploaded audio for consistent loudness. Our leveling algorithm adjusts the audio so that even quieter sections are perceived at the same level as louder ones. This allows you to listen to demos and audio files at a consistent volume regardless of their original levels. We deliver all approved recordings in two dynamically mastered loudness standards plus the original unprocessed audio (there's also an advanced export available for any format/loudness level). This makes it easy to produce loudness-correct web videos without technical expertise.

How to Use Voicemachine Audio in Web Videos

1. Download the -16 LUFS voice-over audio file and import it into your video editor.

2. Do not adjust the volume of this file. The -16 LUFS track will serve as the anchor for all other audio, including music and effects.

3. Add music and effects in relation to the voice-over, ensuring the VO remains clear and prominent. You can apply light EQ to blend the voice-over with other elements if needed but do not change the volume of the voice-over.

4. If your editor supports it, add a limiter at the master output and set it to -1 dB for safety. The master should be set to the default 0 dB.
   

Following this method ensures that your web videos maintain a consistent perceived level and comply with common web loudness standards (typically -16 to -14 LUFS on platforms like YouTube, Vimeo, and social media). No advanced audio engineering skills are required.

Note: Broadcast commercials have stricter loudness standards and tighter tolerances. For best result consult an audio engineer.

Good luck with your video production!
