Revolutions in sound recording
This unit looks at the ways in which technology has influenced the music industry and how this has changed the way we listen to music and buy records. It is a brief history of the recording industry from its beginnings at the end of the nineteenth century. Step changes in technology will be highlighted in a story that often is as much about the people who built the industry and the recordings they made as about the technologies that were developed and used.
Please note that Activity 1 is optional and requires additional materials and software.
This free course includes adapted extracts from an Open University course which is no longer available to new students. If you found this interesting you could explore more free Technology courses or view the range of currently available OU Technology courses.
