WorldCast Offers New Versions of APTmpX

Cites benefits to radio broadcasters

WorldCast Systems announced new versions of its APTmpX, an MPX/composite compression algorithm.

“APTmpX significantly lowers the hardware and distribution costs previously associated with standard FM network architecture,” the company said in the announcement.

“Despite the advent of the internet and digital broadcasting standards, FM remains the world’s most popular transmission format and a central technology in radio broadcasters’ efforts to maximize their reach and audience. As a result, new technologies have had to be created to enable an FM-centric workflow to also work for internet delivery.”

It said the initial version, launched in 2020, offered FM broadcasters access to high-quality signal compression for centralized FM MPX/Composite transmission.

“This provided a game-changing solution in the <900 kbps region,” it continued. “However, the latest release of APTmpX takes this even further.”

Three versions are available that offer levels of compression at 600, 400 or 300 kbps network bandwidth. “This dramatically widens the potential impact of the technology on the industry and means that the composite signal can now directly be transported with non-destructive compression from 600 kbps down to 300 kbps, all at the highest sound quality,” it stated.

Gregory Mercier, director of product marketing, was quoted saying the new versions will particularly benefit broadcasters in areas of poor bandwidth penetration.
