Broadcast media refers to content that is distributed publicly via radio waves or streaming online for anyone to access live without restrictions. In contrast, non-broadcast audio can be paused, rewound or fast-forwarded. Common forms of broadcast media include terrestrial radio, digital audio broadcasting, and internet radio, while podcasts and in-store radio are also considered forms of broadcast. Audio file formats store digital audio on computers and include formats like MP3, WAV and formats used for CDs.
