Do you trust that moving hardware functions to virtual software applications improves business operations?
swXtch.io has released groundSwXtch, a software application designed to transport Audio over IP (AoIP) across standard servers and virtual machines. The release allows for the transmission of formats such as Ravenna, AES67, and ST 2110-30 over WAN, 5G, and public internet connections.
Why it matters
By virtualizing the transport layer of audio streams, the software removes the reliance on physical codec hardware and the corresponding encode/decode latency. This approach enables studios and data centers to form a unified fabric using existing IP infrastructure.
The application supports professional AoIP formats including Ravenna, AES67, and ST 2110-30. It utilizes SMPTE ST 2022-7 hitless failover to provide packet protection during transmission.
The players
swXtch.io
A software company focused on cloud-based networking, virtualized broadcast infrastructure, and IP stream management.
The details
groundSwXtch operates by creating a centrally managed overlay that transports native multicast AoIP streams across standard IP infrastructure. It shares its core architecture with the existing cloudSwXtch platform. By linking studios and data centers into a single fabric, it enables professional-grade audio transport without requiring users to modify their physical network hardware.
Timeline
September 28, 2026: swXtch.io released the groundSwXtch software application.
The Tech Race
This release follows a broader industry trend of shifting broadcast functionality from purpose-built proprietary hardware to software-defined architectures. It extends the capability set established by the cloudSwXtch platform into the specific niche of professional audio networking.
Broadcasters and studios can now deploy AoIP workflows on standard servers or virtual machines rather than investing in dedicated codec hardware. This change allows for faster, more flexible network expansion using existing 5G and public internet connectivity.
The takeaway
The move toward software-only AoIP transport suggests a future where broadcast backbones are increasingly agnostic to underlying hardware. Watch for future benchmarks demonstrating how this overlay handles high-bandwidth traffic compared to traditional hardware-based SMPTE ST 2110-30 implementations.
