Audio ads enable marketers to connect with audiences during screen-free moments in their homes, at work, or when they are out of the home. Audio ads provide an immersive and different engagement experience through various devices, including desktop, mobile, and tablet. 

Audio ads are traded programmatically using a similar method to display/native advertising, Connected TV, OTT, and video, where Audio ads are traded and inserted into audio contents of audio publishers through automated technology as a pre-roll, mid-roll, or post-roll of an audio or podcast.
