Digital technology supports the creation, the recording, and the distribution of audio media by individuals without requiring access to recording studios and radio broadcast stations. Hardware innovations, such as MP3 players, the iPod, and smartphones, have made possible the ability for audiences to listen to audio productions using digital devices. Networks have made possible the distribution of sound beyond the listening distance of speakers and reception of radio signals.
Although audio may be created, recorded, and released via multiple digital formats such as songs or book recordings, one popular digital audio medium that has arisen is the podcast. A podcast is a digital audio recording of speech, auditory effects, music, and even absence of sound. Podcasts often run in series, generally focused on a single topic for a “season” or more generally on particular interests, such as history, technology, design, sports, literature, and so forth. Podcasts may feature one person talking, an interview of one or more people, a series of people talking about a topic, or a combination of these.
Digital audio may be produced for audio-focused projects, such as individual songs or podcasts, but may also be created to be incorporated as part of video games, movies, and digital journalism.
