History of sound recording

Experiments in capturing sound on a recording medium for preservation and reproduction began in earnest during the Industrial Revolution of the 1800s. Many pioneering attempts to record and reproduce sound were made during the latter half of the 19th century – notably de Martinville's Phonautograph of 1857 – and these efforts culminated in the invention of the phonograph, patented by Thomas Edison in 1877.The history of sound recording - which has progressed in waves, driven by the invention and commercial introduction of new technologies - can be roughly divided into four main periods: the ""Acoustic"" era, 1877 to 1925 the ""Electrical"" era, 1925 to 1945 (including sound on film) the ""Magnetic"" era, 1945 to 1975 the ""Digital"" Era, 1975 to the present day.
