The Challenge: Record a Sound or Voice
Page: 1 2 3 4 5 6
How was a recording made?
To make a recording,
or rather an attempt at a recording, the cylinder needed to be turned.
The drawing pin stylus was placed onto the wax so that it pushed
in about 0.5 to 1 mm (0.02 - 0.04 in.). The handle was turned at an even
rate and we shouted into the horn.
we re-adjusted the drawing pin in the wax and used the last half to have
a go at recording under slightly different conditions, hoping that one
of these two recordings would have worked.
