APT IP Codec
Audio over IP Transport

Available on all APT codecs, SureStream ensures perfect audio or MPX delivery over IP by sending multiple stream copies across diverse network paths. Its intelligent redundancy engine reconstructs a flawless, low-latency stream at the receiver end - eliminating dropouts and ensuring true broadcast-grade reliability, even over imperfect networks. 

APTmpX is the industry’s leading composite/MPX compression algorithm, delivering exceptional audio transparency over low-bitrate IP connections. With bandwidth options as low as 300, 400, and 600, it removes the usual trade-off between audio quality and transmission efficiency. APTmpX eliminates the two main barriers to FM MPX migration - high bandwidth requirements and audio degradation - making it the go-to solution for cost-effective, high-fidelity MPX-over-IP transport.

SynchroStream is a GPS-based technology that delivers ultra-stable, synchronized audio transport over IP by removing latency variability within extremely narrow limits. A single encoder latency setting keeps all decoders aligned with millisecond accuracy, with automatic sub-microsecond fine-tuning at each site. Integrated into WorldCast's SFN FM solution, SynchroStream ensures highly accurate time synchronization across overlap zones. Engineers can precisely define the audio alignment point with better than 50-meter accuracy, using delay steps as fine as 125 ns.
