Audio Media: Introduction 

Audio media, such as music and podcasts, share the power to communicate deeply and personally with listeners, often using sound and words to tell stories and set moods. Both forms have been fundamentally changed by digital technology, which has made content abundant and accessible, mainly through mobile devices and streaming. These digital changes mean that algorithms and platform rules are now major forces in deciding what listeners discover and consume. 

Music communicates through lyrics as well as elements like rhythm to suggest emotional feel, while melody forms the main tune. Abrupt changes in these elements, like rhythmic or harmonic surprises, can trigger a physical reaction in listeners called "frisson," or chills. Today, music is often consumed alongside visuals, like in music videos, and is recontextualized in other media such as film and video games. 

Podcasting is a highly flexible audio format that allows for diverse and immersive storytelling, often focusing on intimate conversations. The barrier to entry for production is low, meaning podcasters can use simple devices like cell phones to record content, which has led to a more diverse range of creators compared to traditional media. 

A defining feature of podcasting is the powerful sense of intimacy and closeness it creates. Hearing a host’s voice through earbuds can make listeners feel a one-sided connection, known as a parasocial relationship. This relaxed, conversational environment also makes podcasts effective platforms for political discussions, allowing for ideologies not often found in of mass media to be shared and building trust with listeners.
