Australian FTA broadcasters follow Free TV Australia Operational Practices (OP-59), targeting −24 LUFS integrated, program-gated. That value derives from ATSC A/85, not EBU R128, which sits 1 LU lower at −23 LUFS. Streaming originals platforms measure differently. Netflix targets −27 LKFS dialogue-gated, where loudness is read only across the sections that contain dialogue, and Disney+ specifies the same −27 LKFS dialogue-gated target (±0.4 LU, per its published Media Tech Specs), with Amazon understood to follow the same convention (confirm against Amazon’s current partner spec). Apple TV+ publishes a dialogue-gated acceptance range rather than a single −27 target; Stan and Paramount+ do not publish loudness specifications. A −24 program-gated master and a −27 dialogue-gated master are not interchangeable numbers, so confirm both the target and the measurement method per platform. All platforms apply normalisation on ingest, so deliver to spec regardless of the perceived loudness of the content.

Confidence levels

Medium confidenceBased on industry practice; full spec not publicly documented. Verify with platform before delivery.

Accuracy note — Delivery specifications change and vary by content type, commission, and territory. This reference is based on publicly available technical standards (Free TV Australia Operational Practices, Netflix Partner Help Center, and platform-specific documentation) as of July 2026. Streaming loudness targets in particular vary by content type and are often documented only in partner portals; always confirm current requirements directly with the broadcaster or platform before finalising post-production.
