To understand LUFS, picture a seesaw. When sounds are too low or too high, LUFS helps level them out. Now, every sound plays at a similar volume. No more reaching for the volume knob!
Understanding Full-scale Levels
Full-scale levels relate to the maximum volume. Imagine a cup filled to the top with water. That’s your full-scale level in audio. Zero LUFS is the loudest sound without distortion. Most streaming services recommend -14 to -16 LUFS for the best listening experience. This ensures you enjoy clear and balanced sound.
| Service | Recommended LUFS |
|---|---|
| Spotify | -14 LUFS |
| Apple Music | -16 LUFS |
| YouTube | -14 LUFS |
Understanding LUFS is easy. Just think of it as a helpful guide that ensures sounds are friendly to our ears. With these insights, content creators deliver seamless audio experiences.
