This article aims to make a short history of digital audio taking into consideration a set of technological inventions, scientific research and cultural appropriations. For this, the work will be divided into two sections: the first one will deal with the beginnings of music recording and reproduction technologies, so it will be necessary to go back to the last quarter of the nineteenth century, the period of birth of analog sound machines that, even with their successive techno-cultural mutations –from the phonograph to the record player–, they will domi- nate the music industry scene well into the second half of the twentieth century. Second, the emergence and development of digital sound machines will be addressed, for which we will focus precisely on the process of digitizing analog signals, as well as in the context of the emergence of their favorite children: the compact disc and the MP3.
