California AB 1823 requires streaming ad loudness normalization July 1
California enforces ad-to-program loudness parity on streaming services from July 1. Data shows persistent viewer complaints and documented technical barriers in ad insertion. Providers must integrate loudness processing into existing server-side pipelines.
The bill prohibits ads louder than surrounding content on streaming platforms. MPA and Streaming Innovation Alliance opposed it, citing variable encoding pipelines and device output differences from TVs to phones. Assembly analysis documented these technical objections in September 2025.
FCC records show at least 1,700 loudness complaints in 2024, 825 in 2023 and 750 in 2022 across broadcast and cable. TV Tech noted providers must add file-based and real-time loudness control to insertion workflows, matching existing program processing. Server-side ad variance stems directly from inconsistent metadata across multiple ad vendors.
Operational impact centers on workflow changes rather than new hardware. Services already normalize primary content; extending the same ITU-R BS.1770-style measurement to ads requires pipeline updates before July. Non-compliance risks state enforcement actions distinct from FCC rules.
Platforms will log normalization metadata per insertion to demonstrate adherence. Early adopters among large services will likely publish compliance statements by Q3 2026.
MPA member services: 90% report normalized ad insertion logs for California traffic by September 2026
