EBU R128
The standardized loudness recommendation instituted by the European Broadcasting Union (EBU) to strictly normalize audio levels across platforms.
What is EBU R128?
EBU R128 is a technical recommendation that mandates program loudness normalisation using the LUFS (Loudness Units relative to Full Scale) measurement standard. Rather than measuring peak levels: which fail to capture perceived loudness: LUFS integrates across the full duration of the programme to produce a psycho-acoustically accurate number. R128 specifies a target of -23 LUFS for European broadcast, with strict tolerances above and below.
The practical result of R128 compliance is that advertisers can no longer cheat by mastering commercials several dB louder than the surrounding programming to grab listener attention: the broadcaster's processing chain now pulls everything to the same LUFS target before transmission. Creative teams have adapted by producing ads with dynamic interest and clever opening hooks rather than brute-force loudness.
Why it matters
Specifically developed to eliminate the jarring, unpleasant volume spikes between regular programming and aggressively mastered commercial advertisements in Europe.
