DPP Loudness Requirements: quick guide
Meters set to EBU R128 mode. Integrated loudness over the entire programme should be -23LUFS. Tolerance is ±1LU for post-produced content and ±2LU for live or as-live content. DPP has not specified maximums for Short term and Momentary loudness measurements.
Maximum true peak audio level recommended as -3dBTP. Programmes will be rejected if it exceeds -1dBTP. Recommended loudness range (LRA) is 18LU. Dialogue must be acquired and mixed so that it is clear and easy to understand.
WHAT IS THE DPP?
The Digital Production Partnership (DPP) is an initiative formed in 2011 by the UK's public service broadcasters to help producers and broadcasters maximise the potential of digital production. The partnership is funded by ITV, BBC and Channel 4 with representation from Channel Five, Sky, S4/C, UKTV, BT Sport and the independent sector including UK Screen on its working groups. The DPP leads the standardisation of technical and metadata requirements within the UK broadcast industry.
