RAVENNA – Mixing it up

RAVENNA – Mixing it Up

Last time we connected RAVENNA Virtual Sound Card to the Merging Horus and monitored the output out of the Horus headphone output.

Once the Horus was receiving audio we accessed its set up webpage. We connected another audio input into the AES connection on the Horus and created that as a standard RAVENNA stereo stream output.

We then routed the audio stream out and back into the PC with the RAVENNA virtual sound card. So we had two devices with two different streams.

The basics of this is that with RAVENNA, you set up an audio stream on the source device of however many channels you want to send and that stream is then advertised on the network and any receiving RAVENNA device can then see it.

Its then a snap just to connect that audio at the destination device.

Next steps – more devices

Reeling from the success of connecting up the Horus, in and out we thought we’d add some more devices to the network.

We found that once the switch had been set correctly, it was then easy to add other devices.

Given our love for expensive things, we got hold of a
Neumann KMD digital microphone.

Connecting this into the Neumann DMI-8 which acts as a concentrator for up to eight such microphones. To think if we had eight of these mics and the hub we could buy a pretty decent car

We accessed the DMI-8 webpage and created an AES67 compatible stream and we sent that back to the PC running RAVENNA virtual sound card.

So we now have different audio channels on different devices, running both RAVENNA and AES67 streams simultaneously.

Next time, we’ll actually make some noise and set up some networked loudspeakers
