WorldCast Systems Wins 2022 NAB Show Product of the Year Award for APTmpX


WorldCast Systems announces that its APTmpX is a Radio winner in the  2022 NAB Show Product of the Year Awards. This official awards program recognizes the most significant and promising new products and technologies showcased by corporate partners of NAB Show.

APTmpX is FM’s most superior and versatile MPX compression algorithm to save network bandwidth for STLs – while ensuring high audio transparency and link quality. The first version of APTmpX, launched in October 2020, provided FM broadcasters with access to high-quality signal compression for the resulting centralized FM MPX/composite transmission. The breakthrough solution, in the <900Kbps range, solved the difficulty of ensuring high quality and low-cost transmission. However, the latest version of APTmpX goes one step further. After optimization by WorldCast engineers, three new versions are available, offering new compression levels at 600, 400, and 300 kbps network bandwidth. APTmpX sets the standard for the highest signal fidelity with the best latency performance, making it easy to ensure a consistent sound signature across the transmitter network.

This cutting-edge technology is 100% backwards compatible with the thousands of APT IP Codecs and APT AoIP modules in the field, through a simple software license upgrade.

NAB Show Product of the Year Award winners were selected by a panel of industry experts in 15 categories and announced in a live awards ceremony at NAB Show on April 26. To be eligible for an award, nominated products had to come from companies exhibiting at the 2022 NAB Show and be delivered within the 2022 calendar year.

“The 2022 NAB Show Product of the Year Awards honor innovative breakthroughs that will change the way the media and entertainment industry creates, connects and capitalizes content,” said NAB Executive Vice President of Global Connections and Events Chris Brown. “We congratulate WorldCast Systems on this award in recognition of APTmpX and its potential to help storytellers meet the challenges of today and tomorrow.”

“We are honored for this recognition and proud to showcase such a prestigious award. Our team worked hard to meet the radio market’s needs for this high-value technology. APTmpX is a cutting-edge innovation that brings the power of MPX transmissions to a whole new section of the market, in particular to those with poor bandwidth penetration. With APTmpX, broadcasters in any network infrastructure can now deliver stunning audio quality to their audiences while enjoying the cost-savings of FM MPX transmission,” said Gregory Mercier, Director of Product Marketing.
