Is there any audio ads for iPhone audio apps?

Question

my app is like podcast for web articles. https://apps.apple.com/app/id1273954643

I plan to make a free version and am curious if there is audio ads for iPhone apps. Since most users of my app don't see the screen, banner ads doesn't fit well. I want to insert audio ads like spotify.

I checked http://www.medialets.com/ and http://www.greystripe.com/, but their show cases are quite vague. I sent emails to them, but no reply yet.

Any help will be greatly appreciated.

Thanks!

Hmmm... this seems like an awesome business opportunity that hasn't been properly executed yet.

I have also seen mentions of audio ads being served up into client iPhone apps by TargetSpot.
