Maker includes an audio recording tool that allows you to easily record & add your own audio to your Maker project.
First, you'll open your Maker project and select the Record button in the left panel.
Then select Record Audio.
You can then record your audio using the Record button. Once you're finished recording, select the Stop button.
You can listen back to your recording, and when you're ready, select the blue check mark to begin the Upload process.
You can then locate your recording in the Uploads bin & add it to your project from there!
