Homemade recordings - NOT amateur radio

Some months ago I chanced upon a recording made in the 1960s. It is of my own voice recorded on the plastic lid of a coffee tin made with a school friend! This is pure analogue. My problem is I no longer have a means of playing it.

To this day, I find this fascinating, that just a large horn a piece of plastic or metal and a very loud shout is capable of recording my voice. 60 years later, my teenage voice is still imprinted.

1860 voice recordings

I missed this news from March 2008 about the earliest recordings of the human voice made in France in the late 1850s and early 1860s. American researchers pieced together a 10sec audio clip of a French folk song which they believe is the oldest recognisable recording of the human voice. A young woman sings from the 18th century folk song Au Clair de la Lune. It was made in 1860 by Edouard Scott de Martinville on a device he called a phonautograph. Listen to the sound clip here:

Edison's recording of himself reciting 'Mary had a little lamb' were many years LATER than these very early recordings. Totally fascinating!
