Some of the earliest sound recordings ever made are about to be heard for the first time in over 100 years.
- The New York Public Library for the Performing Arts has unearthed a batch of wax cylinders - an early recording medium developed by Thomas Edison.
- The fragile cylinders are designed to be played on an old phonograph - but researchers have developed a machine that can read them digitally with a laser and needle.
- Some of the cylinders include opera performances, field recordings, and even old birthday party greetings.
- The process of digitizing all of them will likely take years.
- What was your first recording device? Did you have a cassette recorder growing up?
