JackTrip WebRTC: high quality, uncompressed, low-delay audio streaming

"low-delay", "WebRTC" ... choose one.

I really don't get why everything needs to be in a web browser nowadays. WebRTC is simply the wrong choice for low-delay audio streaming. Audinate's DANTE protocol has been around for 14 years, is affordable, hardware-accelerated, and has practically no avoidable latency when sending audio over the network.

Why add 20+ms of latency just to use WebRTC?

Completely agree, while proprietary what Audinate has done with Dante is nothing short or a miracle. With their PCI-E FPA I have less then a 2ms round trip latency with my Hilo interface at 96Khz resolution. Additionally the virtual sound card can do 4ms latency in one direction with most modern CPUs.

Dante is proprietary for one thing.

Here's a GPL implementation https://github.com/jsharkey/wycliffe

Thanks! Have you had any luck running it? It doesn't seem to have any documentation.

Good question; JackTrip normally uses UDP and I think most browsers do not support sending UDP packets directly without an extension.

If you could send UDP directly then WebRTC could presumably be avoided.

Doesn’t webrtc use UDP?

In some cases on some web browsers WebRTC can be configured to use UDP.

But that's exactly the problem. Usually, nobody knows what's actually happening in that 20000+ lines of code WebRTC stack.
