Programmatic Audio is a digital advertising strategy that involves buying and selling ads automatically and in real time on audio platforms such as radio, podcasts and music streaming services. 

Through programmatic audio, advertisers can reach a target audience with audio ads that are relevant to their interests and behaviors. That could include advertising on podcasts that revolve around specific topics, music streaming services where ads are customized by music genres, and radio stations that target specific demographic groups.

The benefits of programmatic audio include targeting based on demographics, geography, behavior and music preferences, and allowing advertisers to reach an engaged audience as they listen to audio content. By automating the buying process and using data analytics, advertisers can also optimize their campaigns and measure performance more effectively.
