How do I add a hyperlink for a recorded questions from Vocaroo? I can't seem to get audioboom working.

We don't have a widget for Vocaroo. You mentioned Audioboom though so I'm assuming you're referring to this widget.

To add it, just place the direct URL of the audio file inside the widget.

Alternatively, just use our iFrame Embed Widget instead and use Audioboom's default iframe embed codes.
