Lightact can use a variety of audio inputs. Usually, it’s for audio analysis and audio visualizations, but you can also just re-route them to an audio output.
The first step in using them is to insert an Audio Input node in the Devices (F7) window.
When the node appears, select the Source device and then check the Streaming checkbox.
A green Connected label should appear.
Setup in Layer Layouts
That’s all we had to do in the Devices window. Now, let’s create a new layer and open its layout.
Insert an Audio Input Reader node and an Audio Player Node and connect them as shown above.
Select the Audio Input Reader node and, in its properties on the right, select the Audio Input node you created in the Devices window.
Then, select the Audio Player node, and in its properties on the right, select the audio output you want the audio to be sent to.
This should be it. If you press play (or hit spacebar) you should hear the audio input on the audio output device you selected.
