# Create an Audio Overview from your sources

> NotebookLM's Audio Overview turns your uploaded sources into a podcast-style discussion between two AI hosts. Generate, listen, and download.

Audio Overview converts your notebook's sources into a podcast-style conversation between two AI hosts. The hosts discuss the main themes and ideas from your material in a back-and-forth format, making it easier to absorb information when reading isn't practical or when you want a quick orientation before going deeper into the sources themselves.

## Use cases

Audio Overview is well-suited for:

* **Commuting or multitasking** — listen to your material while on the go
* **Getting oriented** — hear a high-level discussion before reading your sources in full
* **Sharing with teammates** — send the audio file to colleagues who need a quick overview of the material

## Generate an Audio Overview

<Steps>
  <Step title="Open a notebook with sources">
    Make sure your notebook has at least one source added. Audio Overview draws on all sources currently in your notebook, so add everything you want covered before generating.
  </Step>

  <Step title="Open the Notebook Guide panel">
    Click the **Notebook Guide** button or tab on the right side of your notebook.
  </Step>

  <Step title="Click Generate">
    Click the **Audio Overview** button, then click **Generate**. Processing takes approximately 1–3 minutes depending on the number and length of your sources.
  </Step>

  <Step title="Play the overview">
    When the audio is ready, click **Play** to start listening directly in the browser.
  </Step>
</Steps>

<Tip>
  Add all your sources before generating. Audio Overview is created from everything in your notebook at the time you click Generate—if you add more sources later, regenerate to include them.
</Tip>

## Listening controls

Use the playback controls in the Audio Overview panel to:

* **Play / Pause** — start or stop the audio
* **Scrub the timeline** — click or drag on the progress bar to jump to a specific point in the conversation

## Download the audio file

Click the **Download** button to save the audio file to your device. You can then share it, play it in any audio app, or archive it for later.

## Regenerate

Click **Generate** again to create a new version of the Audio Overview. The previous version is replaced—there is no way to retrieve an older generation after you regenerate.

## Language

Audio Overview is generated in the language of your sources. If your sources are in English, the hosts speak English. Notebooks with mixed-language sources may produce an overview in the predominant language.

<Note>
  Audio Overview covers the main themes and ideas from your sources. It does not read every word of every source—some details, data, or passages may not be mentioned.
</Note>

<Warning>
  Do not rely on Audio Overview as a substitute for reading primary sources in critical, professional, or academic contexts. Listen to it as an orientation tool, then verify key information by reading the original source material.
</Warning>
