LTC Input from Dante

In this tutorial, we will guide you through configuring your system to receive LTC (SMPTE) via a Dante Network

Dante Virtual Soundcard Configuration

Dante Virtual Soundcard (or simply DVS) is an application provided by Audinate that allows you to expose incoming Dante channels as (like the name says) virtual soundcards.

The very first step is to install this application and getting comfortable with it. At the time of this writing, ShowCockpit does not have an ASIO driver for LTC input. Therefore, it is only possible to grab Dante audio input using the WDM driver.

Therefore, WDM as the Audio Interface and click Start.

Route the audio in the Dante Controller

In your Dante Controller, you will see a new Dante device popping up ready to be routed. In the example below, to keep it simple, we have routed the first 16 channels of a stage box into the first 16 channels of DVS.

Example routing in Dante Controller from an Allen&Heath dLive CDM32 into DVS

Configure LTC Input in ShowCockpit

At this point, you can treat the DVS device as a normal soundcard.

  1. Add an LTC Input element (External Control > Timecode > LTC Input)

  2. Configure the Input Device, according to the mapping you have made earlier

  3. Set the FPS according to the project specifications

  4. Set the Sampling Rate to 48000 Hz

  5. Set the Channel to the virtual soundcard channel you want to get LTC from

Below is an example to receive LTC on DVS Channel 16.

Example to get LTC from Dante Virtual Soundcard channel 16

Note the selected Input Device is "DVS Receive 15-16" and the selected Channel is 2 (the second input channel of this virtual device that exposes channels 15 and 16)

Verify if the timecode is correctly received

If you now enable the LTC Input element and double-click it, you should see any incoming TC data running.
