USA ABC Network commercials loudness spec
What a file has to measure to pass this spec, and where each figure comes from.
The ABC Television Network’s Commercial File Delivery HD Technical Specifications (October 2026) ask for −24 LKFS integrated loudness. ABC rejects a spot louder than −23 LKFS, and the lowest it accepts is −26 LKFS. True peak must be no higher than −6 dBTP, stricter than the −2 dBTP usual under ATSC A/85. Both are measured over the whole spot, on all channels except the LFE. LC-1 checks a WAV against this spec in seconds, applies the necessary level change and true-peak limiting, and prints a compliant file.
| Check | Required | In LC-1 |
|---|---|---|
| Integrated loudness | −26.0 to −23.0 LKFS | Fixed with a level change |
| True peak | −6.0 dBTP max | Limited, with audition |
