What is Audio Normalization?

Audio normalization is the process of adjusting the overall loudness of an audio file to a target level, measured in LUFS (Loudness Units relative to Full Scale). Unlike simple peak normalization - which only raises the loudest moment to 0 dBFS - integrated loudness normalization measures the perceived loudness of the entire file and applies a consistent gain adjustment. Our free audio normalizer online uses the Web Audio API to measure RMS-based loudness and apply precise gain to reach your target LUFS level. This is the same approach used by streaming platforms like Spotify, YouTube, and Apple Music to ensure consistent playback volume across all tracks.

什么是 LUFS，LUFS 为何重要？

LUFS 测量声音的听觉音量。流媒体平台如 Spotify（−14 LUFS）、YouTube（−16 LUFS）和广播标准 EBU R128（−23 LUFS）使用 LUFS 目标以确保音量一致播放。将音频设置为正确的 LUFS 可以防止平台自动调整音频。
