Designed for modern broadcasters, it enables high-quality, spectrum- efficient digital transmission across AM, SW, and VHF/FM bands. From content encoding and multiplexing to cloud-hosted delivery and receiver integration, the DRM Stack empowers broadcasters to deliver audio, multimedia and data services — with superior audio fidelity, flexible data capabilities, and low-cost deployment — in both traditional broadcast and next-gen hybrid environments.
