# Audio VAST creative

One thing to remember - Audio creative supports only audio track and video can't be used.

<span style="font-weight: 400;">The audio file itself usually has the following requirements:</span>

- **Format:**<span style="font-weight: 400;"> MP3, WAV, WMA or OGG</span>
- **Bitrate:** <span style="font-weight: 400;">at least 128 kbps</span>
- **Size:** max <span style="font-weight: 400;">50mb</span>


**Duration:** <span style="font-weight: 400;">15 to 30 seconds mostly, with very limited inventory supporting 60s creatives</span>

To create Audio creative, please follow these steps:

**Step 1:** Log in to your DSP account, go to ***Creative Sets***, and click ***Add creative set***.

**Additionally:** Audio creatives (10-30% of the current audio inventory, depending on country) also supports companion banners (static(95%) and HTML/JS(5%)). For simple display ad - just upload it by selecting "Choose files". Fo HTML/JS - add creative dimensions and upload/paste creative tag.

We support one companion-ad per creative. Companion should be one from most popular sizes - 300x250px, 320x480px, 480x320px.

In audio campaign report, under "Event metrics" we will see "Companion impressions" and "Companion clicks" companion ad performance metrics (if available).
