The 19th edition of the publication arrives at a critical time
WorldCast Systems has upgraded its APTmpX non-destructive MPX/composite compression algorithm, which it introduced in 2020. With a compression level of <900 kbps, APTmpX is designed to help broadcasters overcome the difficulty of maintaining both a quality and a cost-effective FM transmission.
The company has now optimized APTmpX’s performance even further by introducing three new versions that offer levels of compression at 600, 400 or 300 kbps network bandwidth.
This, explains the firm, 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.
“Thanks to its low complexity and easy integration, APTmpX has already proven itself as the ultimate solution to enable a 100% digital transmission chain, bridging the transition from digital studios to digital transmitters,” said Gregory Mercier, director of Product Marketing, WorldCast Systems.
“With these new versions, we bring its power to a whole new section of the market, allowing broadcasters in areas of poor bandwidth penetration to deliver stunning audio quality to their audiences no matter what they are listening on.”
