The first human recording was made by the phonautograph utilizing purely analog methods, also known as acoustic recording. In this brief review we will visit the history of sound, from the primitive yet ingenious beginnings, the patent race of the late 19th century, all the way to the technological boom brought forth by the first and second world wars. Analog technology has seen the most diverse, complex and innovative developments over the past 100 years. Yet not every invention achieved the approval of the masses, becoming somewhat forgotten in the shadows of the successful mediums we've all come to know. Let's celebrate the failures of the past that have paved the way for ongoing excellence in sound recording and sound reproduction.
