RƎLAY VPB

Click. Connect. Broadcast.

PC audio handling is so limited. Bridging the gap between audio apps, sound cards and broadcast hardware was nearly impossible — until RƎLAY Virtual Patch Bay.

Now you can easily route audio between your PC’s audio apps and hardware audio devices. Even natively route AoIP streams. RƎLAY VPB displays them all in an intuitive matrix that lets you patch sources and destinations with just a click. Mix and combine multiple sources. Build custom routing environments. Even loop in third-party VST processing plugins.

RƎLAY VPB fully supports virtualized platforms like VMware and cloud-based environments such as AWS and Microsoft Azure. In addition, RƎLAY VPB can be deployed as a gateway service, converting multicast local-area streams into point-to-point unicast streams, more applicable for wide-area connections and cloud platforms.

RƎLAY VPB is the missing Link you’ve been waiting for.

RƎLAY Virtual Radio Software Brochure

RƎLAY is more than just studio software — it’s a complete Virtual Radio environment for Windows, with touch-based mixing, intuitive graphical patch bay, RAVENNA multi-channel soundcard replacement, and a comprehensive AoIP stream monitoring package. RƎLAY is real virtual radio.

Intuitive Control

Get in the Loop

Each connection’s input and output levels can be separately controlled. You can even insert VST apps like an effects loop, to process audio during routing.

Point, Click, Route

RƎLAY VPB is easy to learn and use, because it resembles a familiar patch panel. All of your audio sources are presented in an instantly understandable matrix view. Just click the crosspoints to connect.

Connect Everything

RƎLAY VPB routes everything: physical devices like mics and sound cards, software sources like playout software, VoIP clients and IP Codec apps, and RAVENNA streams from AES67 networks — all color coded for quick identification.

Mix and Match

VPB does more than just patch — you can also mix multiple sources and route them to single or multiple outputs.

Highly Logical

RƎLAY VPB has a Boolean logic engine that gives you full control of how your audio devices interact. After audio sources and destinations are defined, switch to Logic View. Signal layouts and logic connections can be built and saved independently of audio components, helping you easily visualize logic flows. When new audio hardware connects to the VPB PC, or different audio software is used, those components are easily added to the existing configuration; open-source Ember+ control protocol makes it simple to pass logic commands back and forth.

Route AoIP? Of course.

AoIP networks are part of every modern radio facility. And because AoIP is computer-based, RƎLAY VPB gives you the ability to route network streams via your PC’s Ethernet port.

Lawo believes in standards, too, so RƎLAY VPB is 100% AES67 compliant thanks to RAVENNA, the standards-based advertising and discovery protocol with AES67 baked in. A single connection between PC and network, and you’re ready to start mixing, matching and patching. And for peace of mind, VPB supports the ST2022-7 standard for Seamless Protection Switching, ensuring fail-safe link backup to your AoIP network.

Build it with VPB

RƎLAY VPB plus your playout software equals a playout server. Connect it to your mixing console or router using AES67 / RAVENNA. You can run other apps, like recording or editing software at the same time — just patch their outputs through RƎLAY VPB to route the signals to your AoIP network. Bonus: install a hardware sound card in your server PC and run it in parallel to VPB for local monitoring, or for dual-redundant outputs.

 

Run RƎLAY VPB on a server to connect multiple software stream encoder instances. Incoming audio signals can be processed by plugins from the Lawo Processing Suite (or your favorite VST) before distribution to multiple encoders. RƎLAY VPB‘s extensive metering capabilities can display peak and loudness levels for all signals at once. Want to record airchecks of encoded streams? Easy: just route audio to the encoder and recorder apps simultaneously.

 

Run RƎLAY VPB on your studio’s playout PC. Add other broadcast apps – remote codecs, VoIP clients, audio processing. Voila — a Virtual Studio. Today’s powerful COTS PCs can run multiple apps simultaneously, saving the costs associated with studio hardware and fully leveraging the power of your playout PC. Using RƎLAY VPB’s Ember+ logic capabilities, these audio apps can be started automatically on demand, their outputs routed to any endpoint in your AES67 / RAVENNA network.
