Netherlands broadcast radio commercials (Ster) loudness spec
What a file has to measure to pass this spec, and where each figure comes from.
| Check | Required | In LC-1 |
|---|---|---|
| Integrated loudness | −23.0 ±0.5 LUFS | Fixed with a level change |
| True peak | −1.0 dBTP max | Limited, with audition |
| Max momentary | −15.0 LUFS | Flagged |
| Format | 48 kHz | Flagged |
Worth knowing
Other Dutch radio groups differ. Talpa asks for a −6 dBFS peak and gives no loudness figure. The source gives no tolerance: ±0.5 LU is LC-1’s own working window.
