Add real-time audio transport to apps without building the network audio layer yourself.
Roc StreamingOpen-source ecosystem for real-time Audio over IP
Roc Streaming is an open audio backbone for real-time streaming over IP networks, built for controlled latency and resilience across wired, wireless, and wide-area networks.
01The challenge
Make network audio feel like a cable
Sending audio over Wi-Fi, LAN, or the Internet is easy. Making it feel like a direct cable between audio devices is a challenging task.
A cable gives you predictable latency, stable quality, and no audible dropouts. A network adds jitter, packet loss, and unpredictable latency.
Roc Streaming is an implementation of real-time audio transport designed to close that gap: controlled latency, loss recovery, clock handling, and synchronization over standard IP networks.
Cable
- ✓Predictable latency
- ✓Stable signal
Network
- ✗Jitter and packet loss
- ✗Quality competes with latency
- ✗Latency drift
Roc Streaming
- ✓Bounded latency down to 10ms
- ✓Robust HD-quality audio
- ✓Resilient transport with loss repair
02Who it is for
For apps, devices, and audio systems
Roc Streaming is for people who need to move audio between software, devices, rooms, or locations over ordinary IP networks, without relying on a proprietary transport stack.
Embedded & product teams
Build speakers, receivers, streamers, soundbars, and audio appliances on top of an open transport core.
System integrators
Deploy zoned audio across offices, retail, hospitality, schools, gyms, venues, and other shared spaces.
Remote audio workflows
Send audio between rooms, sites, or locations for monitoring, IFB, rehearsal, collaboration, and inter-site workflows.
Open-source & DIY users
Build custom multi-room setups or connect Roc to Linux, macOS, Android, and community-built audio systems.
03Open ecosystem
Layered, fully open ecosystem
Roc Streaming lets you choose the right level of control: use Roc Cast as a ready-to-use application, RocD as a deployable audio service, or Roc Toolkit as the foundation for fully custom real-time audio systems.
Open and embeddable
Fully open source, vendor-neutral, and licensed under commercial-friendly MPL-2.0 license.
Choose your layer
Choose the layer that matches your needs: application, service, or library.
Works with your stack
Use Roc from C, C++, Rust, Go, Java, or through RocD’s HTTP API.
OS audio integration
Connect Roc to existing audio systems through OS audio stacks or virtual devices.
04Audio core
Built on a specialized audio core
At the core of Roc Streaming is Roc Toolkit, the specialized transport foundation behind its real-time audio capabilities.
High-quality audio
Streaming of CD- and HD-quality audio, from uncompressed PCM to lossless or lossy codecs.
Controlled latency
End-to-end latency down to 10 milliseconds, with strict latency bounds and adaptive tuning for changing networks.
Loss recovery
Recovering of lost packets without quality drop using Forward Erasure Correction codes or masking losses with Packet Loss Concealment algorithms.
Adaptive by default
Uses sensible defaults and adaptive algorithms for typical networks, with low-level controls available when your use case needs precise tuning.
Portable and fast
Efficient lightweight core designed for real-time. Portable across OSes and CPUs, including embedded, desktop, and mobile platforms.
Open standards
Built on the foundation of open Internet standards, proven over time and validated by numerous applications.
