What California’s Streaming Loudness Regulation Means For Broadcasters And Ad Tech

California’s SB 576, effective soon, mandates that ads in streaming content be loudness‑matched to the surrounding program, extending the CALM Act principles to digital platforms. The law places compliance responsibility on the entity delivering the ad to California viewers, exposing the fragmented ad‑tech supply chain that currently leads to volume spikes. To meet the rule, broadcasters and ad‑tech vendors must embed automated loudness measurement and correction at ingest, preserving metadata through transcoding. The move signals a broader shift toward universal audio standards for streaming, with potential ripple effects across other states and federal regulation.
