>> AES67 Software Stack

Welliver Tech’s AES67 Audio-over-IP software stack enables NXP i.MX RT microcontrollers to stream high-quality, synchronized audio over standard Ethernet networks. Designed for resource-constrained embedded systems, this solution delivers full AES67 compliance, including real-time audio transport, clock synchronization, and session discovery.

Ideal for professional audio equipment, intercoms, conferencing devices, and AV-over-IP endpoints, this software stack transforms NXP i.MX RT devices into fully interoperable AES67 audio nodes.
