APTmpX Software Benefits


Enables 100% Digital Transmission Chain
With The Lowest Complexity

The complete digital signal path from the studio to the analog RF carrier of the transmitter represents the pinnacle of quality for analog FM broadcasting. APTmpX offers an ideal solution for this transition, featuring low complexity, minimal latency, and straightforward integration to seamlessly connect your digital studio with your digital transmitter.

Protects Sophisticated Sound Processing

APTmpX preserves the integrity of the original MPX/composite. 
It ensures that the rich sound quality of your high-end MPX/composite integrator remains intact.

Hardware Savings and Sonic Signature

By transmitting a centrally generated MPX/composite signal, most MPX composite equipment at transmitter sites is no longer needed. APTmpX Software offers high signal fidelity with optimal latency performance, ensuring your sonic signature is consistently maintained across the entire transmitter network.

Save Network Bandwidth

APTmpX is a multiple award-winning bitrate reduction algorithm designed to save network bandwidth while transmitting consistent MPX/composite signals. With APTmpX Software, you benefit from the APT technology to transmit the final MPX/composite signal at 300, 400, or 600 Kbps.
