Allow microphone error with web object audio recorder

I've been trying to embed an audio recorder into Articulate Storyline like Vocaroo without having it open up in a new window but every time I do it gives an error message saying that it needs microphone access.  I'm hosting my course on a website that I then have clients access on an iPad.  I changed my settings to allow Safari to allow access without asking on the iPad but still receive the error.  It only works when I have it open in another window and still it has to ask to allow each time it triggers.  Any thoughts?
