A later guitar sound of a few notes was recorded was done by using the phonograph type invented by Thomas Edison on 18 July 1877, which used phonograph cylinders as a recording medium.

A recording made on a sheet of tinfoil at an 1878 demonstration of Edison's phonograph in St. Louis, Missouri, has been played back by optical scanning and digital analysis. A few other early tinfoil recordings are known to survive, including a slightly earlier one that is believed to preserve the voice of U.S. President Rutherford B. Hayes ...
An audio format is a medium for sound recording and reproduction.The term is applied to both the physical recording media and the recording formats of the audio content—in computer science it is often limited to the audio file format, but its wider use usually refers to the physical method used to store the data.
1921 : First commercial AM radio Broadcast made by KDKA, Pittsburgh, PA; 1925 : The Victor Orthophonic Victrola Phonograph was invented. A far superior product in comparison to other phonograph manufacturers was an acoustic sound design that was far superior to current offerings.
The groove usually starts near the outside edge and ends near the center of the disc. The stored sound information is made audible by playing the record on a phonograph (or "gramophone", "turntable", or "record player"). Records have been produced in different formats with playing times ranging from a few minutes to around 30 minutes per side.
