The Gray Audograph was a dictation machine format introduced in 1945. It recorded sound by pressing grooves into soft vinyl discs,[1][2] like the competing, but incompatible, SoundScriber. It was manufactured by the Gray Manufacturing Company of Hartford, Connecticut, United States.

The Audograph recorded on thin vinyl discs of 15cm diameter, recording from the inside to the outside, the opposite of conventional gramophone records. Unlike conventional records, the disc was driven by a surface-mounted wheel. This meant that its recording and playback speed decreased toward the edge of the disc (like the Compact Disc and other digital formats), to keep a more constant linear velocity and to improve playing time,[3] which was ten minutes.[4]
In 1950, Gray began to make a variant of the Audograph for AT&T, known as the Peatrophone; however, due to what at the time were the high costs of renting and installing the machine, it served only a niche market.[5]
