Digital media is pervasive in our society, long since edging out analog media such as records and tapes. Despite this, digital media is, for many people, a mysterious entity that somehow produces music or video from a bunch of numbers.

This presentation will de-mystify digital media, explaining how music and video get transformed from a collection of numbers to images and sound. Digital signal processing will be explored, followed by music information retrieval. Video object detection will be introduced as well. Finally, the presentation will explore some of the myriad ways that information about digital media — metadata — is being used to further change how we view and listen to media.
