# Audio
## Receiving Audio
### Setup in the Devices window
In order to create a device, right-click on the *Devices* window and choose **Audio Input.**
Under the *Stream* collapsible header choose which audio input you want to use and click **Receive** if you want to start receiving audio data.
### Receiving Timecode (LTC)
With only the **Audio input** device it is possible to receive timecode (LTC). All you need to do is choose proper input under the *Stream* collapsible header, click **Receive,** then click **Parse LTC** and start your timcode (LTC) sender.
{% hint style="warning" %}
If LightAct doesn't seem to detect LTC, please check that the volume of your LTC source is high enough.
{% endhint %}
You can also set a timecode offset, which will affect all subsequent operations with this timecode.
## Playing Audio
### Setup in the Devices window
In order to create a device, right-click on the *Devices* window and choose **Audio Output.**
Under the *Stream* collapsible header choose which audio output you want to use and click **Play** if you want to start playing (sending to the output) audio data.
### Setup in the Layouts window
{% hint style="info" %}
**Good to know:** in most cases you will be using [Audio layer template](/layers-and-layouts/stock-layer-templates/content-layer-templates/audio-template.md) to play audio.
{% endhint %}
If you want to build a layer that can play audio from scratch, you would first need to create a **Blank layer**.
Then you would want to create a node called **Play Audio (from Asset)**. Then you just need to connect it the way you want.
