Audio recordings can be used for multiple purposes, from narrating content, instructions and explanation to providing recorded feedback.
One of the most popular use of audio recording in recent years has been the production of podcasts. Podcasts can be described as on-demand radio shows that are distributed over the internet, and are usually free to access. Like TV shows, podcasts usually have seasons and episodes. Podcasts have good entertainment value, but most of the successful ones are highly educational.
While podcasts tend to be episodic, audio recordings can be used just as successfully as part of teaching, even if they are targeted to specific activities, rather than being released on a schedule. Many of the basic recording principles will apply regardless of whether podcasts series or individual recordings are recorded.
