With the Sound interaction, it is possible to add sounds to your video. You can use this, among other things, to add background sounds to your video, like a doorbell or a ‘pling’.
Keep in mind that these sounds cannot be edited in HiHaHo, this will require a different tool.
Make sure that the audio file is in MP3 format and does not exceed the 1MB limit, and you’re good to go.
Adding sounds to Questions and Pause Screens.
You can also add sounds to Questions and Pause Screens. This way, you can add a (short) voice-over with just one click. These sounds can be added using the ‘Select a sound’ button in the interaction editor.
