You need to have a Professional plan or higher in order to add audio directly to the timeline.
In this article, we will learn how to work with Powtoon's new audio control. Each aspect of the audio control will have a manifestation on the timeline which allows for additional control.
Adding audio to the timeline allows extreme precision when timing different voiceover files playing in unison with characters and objects onscreen. This will also allow you to add additional audio files to the same slide.

There are three ways to add Audio Controls to your Powtoon.
Voiceover or Soundtrack or Sound effect
Important:
1) In the Powtoon Studio, you need to be working in Create mode in order to add audio directly to the timeline.
Adding a Voiceover to a single Slide
- Select the voiceover you wish to use in your Powtoon. You can use a new voiceover, or use one saved in the My Voiceover section of the Audio tab.
- Select This Slide. The entire voiceover will be added, and your slide will automatically be extended to accommodate the voiceover if needed.

Once you have added the voiceover to the timeline, you can customize it even further.
Adding a Soundtrack to a single Slide
- Select the soundtrack you wish to use in your Powtoon.
- Select This Slide.
- If the Sound is longer than the slide, you will have two options to choose from, that will determine how the sound will appear on the slide.
Extend Length: This will automatically increase the total length of the slide, to accommodate the soundtrack.
Trim Sound: This will automatically trim the sound, so that it will fit onto the slide.
Additional Customization
Once you have added a sound to the timeline, you will have the option to continue customizing your sound.

- Move the sound along the timeline, to change the start and end times.
- Swap: This will allow you to choose a new sound.
- Volume : Adjust the volume for this specific sound.
- Automatically reduce the volume of main soundtrack during playback.
