# Audio Impression Pixels

> [!TIP]
> **Tip:** For some background information on third-party impression trackers, see these Help Center Knowledge Base articles: • [Explainer: Third-party Trackers and Validation Tags](/user/docs/third-party-trackers-validation-tags) • [Working with Third-party Creative Trackers](/user/docs/3rd-party-creative-trackers)

You can add audio impression pixel tracking elements to each ad unit in your creative. You can use audio **impression** trackers, which report an official impression back to the ad server, as well as up to five "**quartile**" pixels that are used to measure the amount of the ad that was heard by the listener. You can include **macros**. For more information, see [Using Macros](/user/docs/using-macros).

> [!NOTE]
> You can also add tracking pixels to [ad unit banners](/user/docs/scripts-and-code-blocks).

## Adding Tracking Pixels

Add the audio pixel URLs on the **Tracking pixels tab** of the ad unit.

**For each pixel:**

- Select the **pixel type**.
- Give the pixel a **name** (optional).
- Enter the **pixel URL**.

Click **Add audio impression pixel** to add additional pixels.

#### Pixel types

- **Impression:** Reports an official impression back to the ad server.
- **Quartile Pixels**:
  - **Start:** Reports that the creative within the ad was loaded and playback began.
  - **1st quartile:** Reports that the creative played continuously for 25% of the total duration at normal speed.
  - **Midpoint:** Reports that the creative played continuously for 50% of the total duration at normal speed.
  - **3rd quartile:** Reports that the creative played continuously for 75% of the duration at normal speed.
  - **End:** Reports that the creative played to the end at normal speed.

For more information on quartiles, see [Quartile Reporting](/user/docs/quartile-reporting).

## Previewing Pixels

Once a flight’s creative includes audio impressions tracking pixels, you can preview the pixels from the **Creatives** section of the flight page by clicking the **Tracking Pixel preview** icon.
