What does integrated LUFS tell me?
Integrated LUFS describes the perceived loudness across the complete recording. A reading closer to zero means louder audio. Use it to compare finished files, then check the peaks before changing gain.
Measure the full mix
A short excerpt may not represent the complete song or episode. Analyze the file you intend to publish. Silence and very quiet recordings may not produce an integrated reading; their peak and RMS readings can still help you diagnose the level.
