How Volume Normalization Works (And Why It Matters)

Not all volume adjustment methods are created equal. Here’s a breakdown of the main standards used by the tools above:

1. ReplayGain

• Supported by tools like MP3Gain, foobar2000, and MusicBee.

2. LUFS / EBU R128

• Used by Spotify, YouTube, and Apple Music.
• Measures perceived loudness instead of just peak volume.
• Common in podcast editors and streaming prep tools like Auphonic.

3. Peak Normalization

• Adjusts audio based on the loudest part of the waveform.
• Simple but doesn’t account for how loud something feels.
• Found in editors like Audacity and GoldWave.

4. Apple Sound Check

• Apple’s built-in normalization, similar to ReplayGain.
• Only works within iTunes/Apple Music.
