Broadcast Loudness Mastering: EBU R128, ATSC A/85, and TV Delivery
Broadcast mastering targets strict loudness standards. Learn EBU R128 (−23 LUFS), ATSC A/85, true peak limits, and how broadcast differs from music streaming.
Broadcast mastering follows stricter loudness standards than music streaming. In Europe, EBU R128 targets −23 LUFS integrated for program material. In the US, ATSC A/85 specifies −24 LKFS (equivalent measurement) for television. Music streaming targets (−14 to −16 LUFS) do not apply.
Key takeaways
EBU R128 (EU): −23 LUFS integrated ±0.5 LU tolerance for broadcast
ATSC A/85 (US TV): −24 LKFS with dialogue-based measurement for mixed content
True peak: typically −1 to −2 dBTP for broadcast encode headroom
Music-for-TV sync often needs both a streaming master and a broadcast-compliant version
How broadcast differs from streaming
Streaming platforms normalize music to roughly −14 to −16 LUFS. Broadcast chains enforce tighter standards so commercials and programs match across channels. A music master at −10 LUFS will be heavily turned down for TV placement.
Measuring correctly
Use a meter compliant with BS.1770-4 / EBU R128 mode — not a standard music LUFS meter on the wrong integration setting. Report integrated loudness, loudness range (LRA), and true peak. See Metering Guide and LUFS Explained.
