How to Create a Voiceover Audio File

AdPipe's AI Voiceover tool lets you generate professional narration directly in the editor. This guide walks you through a quick workflow to produce a clean voiceover audio file you can use anywhere.

Step 1: Create a Black Video

Because AdPipe is a video platform, your voiceover needs a video to pair with. The black video acts as a neutral base you can layer under other clips whenever you need it.

Log in to AdPipe and open the editor.
Create a new project.
1. A new project starts with a black background by default. No need to add clips or a shape.

Step 2: Add Your Voiceover

With your black video in place, you can generate and attach your voiceover directly from the editor.

In the editor, add the Voiceover element under Canvas Settings.
Type, paste, or use AI Scriptwriter to generate your script in the text field.
Preview the available voices and select the one that fits your content.
Play it back, adjust your script if needed, and regenerate until you're happy with the result.
Press Generate. Your voiceover will automatically appear on the timeline.

Tip: You can edit your script and regenerate the voiceover as many times as needed before downloading.

Step 3: Download Your File

Once your voiceover is ready, download the project from AdPipe. The file will export as an .mp4 containing your black video with the narration audio track embedded.

When your voiceover is final, click Generate and your black video asset with the VO overlay will appear in the asset library.
Click the Download button on the asset.
Save the exported .mp4 file to your computer.

Step 4: Convert to MP3 (Optional)

If you need a standalone audio file, such as an .mp3 for a podcast, e-learning platform, or audio asset library, you can extract the audio from your downloaded .mp4 using a free conversion tool.

A few tools that work well for this:

CloudConvert (cloudconvert.com) — browser-based, no install needed.
Adobe Express Audio Converter — straightforward MP4-to-MP3 conversion.
Online-Convert.com — supports multiple output formats including WAV and AAC.

General conversion steps (these vary slightly by tool):

Open your chosen conversion tool in a browser.
Upload your .mp4 file.
Select MP3 (or your preferred audio format) as the output.
Convert and download your audio file.

Note: AdPipe does not natively export audio-only files. The MP4-to-MP3 conversion step happens outside of AdPipe using a third-party tool of your choice.

What voices are available? You can preview a range of AI-generated voices with different tones and dialects. Select the one that fits your project best before generating.
