The **Audio Livestream** trigger is for workflows that should listen to a live audio source instead of waiting for an uploaded file or a published feed item. Use it for always-on streams, live radio, Icecast/Shoutcast sources, direct audio URLs, or playlist-based streams. ### Schema * **Input**: A livestream URL * **Output**: Recorded livestream content for downstream workflow nodes If no recording schedule is set, the workflow records continuously whenever it is active. Add a schedule when you only need specific live windows. ## Add the node Open **Workflows** from the left sidebar and click **New** to open the workflow builder. In the **Trigger** stage, choose **Audio Livestream**. Overlap adds the trigger node to the canvas, selects it, and moves the left panel forward to **Editing** so you can continue building the workflow. Click the **Audio Livestream** field inside the node on the canvas whenever you need to reopen its settings on the right side. Audio Livestream node settings panel ## Configure the livestream In the right-side settings panel, fill in **Livestream URL**. The current settings panel lists these supported livestream formats: * HLS streams, such as `.m3u8` * Live radio stations * Icecast/Shoutcast streams * Direct audio streams, such as `.mp3`, `.aac`, or `.ogg` * Streaming playlists, such as `.m3u` or `.pls` Until the URL is added, the node shows **Incomplete** on the canvas. ## Set a recording schedule By default, the settings panel shows **No schedules defined. Records continuously.** It also estimates about `720 hours/month` for continuous recording and recommends adding a schedule to avoid recording all the time. Click **Create Schedule** when the stream should only record during planned windows. Audio Livestream recording schedule settings The schedule form lets you define the recording cadence with fields such as **Frequency**, **Timezone**, **Start Date**, **End Date**, **Repeat every**, **On**, and **Time**. ## Build the rest of the workflow After the trigger is configured, continue in **Editing** with nodes such as [Find Clips](/nodes/findclips), [Add Audiogram](/nodes/audiogram), [Add Subtitles](/nodes/subtitles), or [Reframe](/nodes/reframe). Finish with an export node, then click **Publish** when the workflow is ready to record from the livestream.
