Understanding the LUFS Standard

When it comes to delivering audio for podcasts, audiobooks, or even radio, you’ve probably heard the term LUFS thrown around.

But what does it really mean, and why should you care?

The simple answer: LUFS (Loudness Units Full Scale) ensures your audio sounds consistent across different platforms, from Spotify to Audible.

Here’s a breakdown of what LUFS is and why it matters for your productions.

1. What is LUFS?

LUFS is a loudness measurement standard that helps determine how “loud” your audio is, not just in terms of peak volume, but perceived loudness.

While traditional meters measure peak volume (how loud the loudest sound is), LUFS measures the overall loudness that your listeners will actually experience.

Why it matters: With LUFS, you can avoid having your audio too quiet (which forces listeners to turn up their speakers) or too loud (which might distort). It ensures a consistent, pleasant listening experience, no matter where it’s being played.

2. Target LUFS for Different Platforms

Different platforms have different loudness targets, and hitting those marks will make your audio sound more polished. For instance, podcasts are typically delivered around -16 LUFS, while audiobooks should aim for around -18 LUFS.

Make sure you research what LUFS you should be aiming for depending on what type of audio content you're putting out there.

How to do it: Use a LUFS meter, which most editing softwares have built in, to measure your overall loudness.

Adjust your compression and limiting settings to ensure you hit the target for each platform you’re delivering to.

Keep in mind, too much compression can result in a squashed sound, so aim for balance.

3. How LUFS Affects Your Audio Quality

Getting your LUFS right isn’t just about making your audio the right volume. It also affects clarity and dynamic range.

If your LUFS is too high, your audio may end up sounding over-compressed, lifeless, and harsh. On the flip side, if it’s too low, it might sound weak or distant.

How to do it: Focus on achieving balanced dynamic range. Don’t sacrifice clarity for volume. Use a limiter to raise the overall loudness, but be cautious not to overdo it.

The goal is to deliver audio that feels loud enough without feeling artificially boosted.

Hitting the right LUFS target can feel like a small detail, but it’s one that has a big impact on the final sound of your podcast, audiobook, or any audio production.

Use the standard as a guideline, and make sure your audio is loud enough without overdoing it.
