Sigma Audio Networks, Powered by MediaCo, Launches InterWave Digital Audio Network Reaching 210 Million Monthly Unique Users

New platform delivers transparent, high-performing audio inventory connecting brands with multicultural audiences across mobile apps, web environments, and digital audio platforms.

NEW YORK--(BUSINESS WIRE)--Sigma Audio Networks, powered by MediaCo, today announced the launch of InterWave, a new digital audio network designed to connect advertisers with multicultural audiences across premium digital audio environments at scale.

Operating under the Sigma Audio Networks umbrella, InterWave provides advertisers access to more than 210 million monthly unique listeners across a curated network of premium digital audio inventory delivered through mobile apps, web players, and other digital listening environments.

Built to extend Sigma Audio Networks’ national terrestrial footprint into the digital ecosystem, InterWave enables brands to activate campaigns across both broadcast radio and digital audio platforms through a single, unified network.

The platform delivers 100% transparent premium inventory within brand-safe, sound-on environments where listeners are highly engaged. With an average 93% completion rate, InterWave connects advertisers with active audiences during peak engagement moments.

The launch comes as advertisers increasingly seek scalable ways to connect with America’s fastest-growing consumer segments.

Today, multicultural audiences represent more than 40% of the U.S. population and more than $7 trillion in purchasing power yet remain significantly underrepresented in scalable digital audio advertising offerings.

“Audio consumption continues to grow across digital platforms, but multicultural audiences remain underserved in many digital advertising ecosystems,” said Elisa Torres, President & CEO of Sigma Audio Networks. “InterWave changes that. By combining premium digital audio environments, transparent inventory, and advanced targeting capabilities, we’re giving advertisers a powerful new way to reach diverse audiences with measurable impact.”

MediaCo’s audience plays a central role in powering the scale and cultural relevance of the InterWave platform.

“MediaCo’s heritage stations have long been trusted voices within multicultural communities, building deep relationships with audiences that engage with our content every day,” said Albert Rodriguez, President & CEO of MediaCo. “Through InterWave, that audience reach now extends into the digital audio ecosystem, allowing advertisers to connect with our listeners across mobile, web, and other digital environments while maintaining the authenticity and cultural connection that our stations have built over decades.”

The launch of InterWave represents a major step in Sigma Audio Networks’ broader strategy to build the most comprehensive multicultural audio platform in the United States, spanning terrestrial radio networks, digital audio distribution, and culturally relevant programming.
