APTmpX is the world’s first and only MPX/composite algorithm to save network bandwidth without deconstructing the original composite signal.
APTmpX offers the perfect balance between maintaining high quality and cost-effective transmission. With 900kbps or even less bandwidth requirement, narrowband IP connections, and in conjunction with APT's SureStream technology, the Internet can be used with confidence. APTmpX can be used without restrictions, be it in the digital or analog audio domain.
With this new technology, FM broadcasters now have access to high-quality signal compression for FM MPX/Composite transmission.
APTmpX is included as a standard format in the MPX license cost and is available in all MPX/composite compatible APT IP codecs.
"With APTmpX, we provide a perfect solution for FM MPX/Composite transmission without deconstruction of the existing composite signal. APTmpX not only enhances our portfolio for MPX solutions, but also marks a milestone in the transition to an MPX/composite environment. We are committed to high quality, low latency, and minimal complexity and this solution meets our brand’s quality standards. In the end, the user benefits from significantly lower hardware and distribution costs while maintaining the station sound."

APTmpX is the world's first bitrate reduction algorithm to save network bandwidth for the transmission of consistent MPX/composite signals. APTmpX allows you to transmit the final MPX/composite signal at 900 Kbps or less, including over narrowband DSL connections.
By transmitting a centrally generated MPX/composite signal, the majority of MPX composite equipment at all transmitter sites is eliminated. APTmpX combines high signal fidelity with the best latency performance and makes it easier than ever to guarantee your sonic signature consistently across the entire transmitter network.
APTmpX does not deconstruct the composition of the original MPX/composite and does not need to reconstruct it at the receiver. Instead, APTmpX maintains the rich sound of your expensive MPX/composite integrator.
As an integral part of the APT codecs, APTmpX processes and transmits all existing signal types. Be it analog or digital audio, or a combination of both, as well as GPIO signals and serial AUX data for the embedded transmission of switch commands or RBDS/RDS information.
The end-to-end digital signal chain from the studio up to the analog RF carrier of the transmitter is the culmination of all quality claims for analog FM broadcasting. APTmpX, with its low complexity, low latency, and easy integration, is the ultimate solution to bridge the
transition from your digital studio to your digital transmitter.
