Voice Recorder is an audio recording program included in most versions of the Microsoft Windows family of operating systems.
It has taken a bit of time to dig back to the origins but we believe that we have found some of the earliest call recorders.We think that this is the earliest telephone voice recorder. There may have been earlier devices which recorded Morse code from the telegraph system, but they don’t really count.
Here is a patent from 1903 of the first telephone answering and recording machine.The patent states that “Our invention relates to telephony, our to more particular object being to provide automatic mechanism for answering calls in the absence of the operative in charge of the station and for automatically recording messages received from the line.”
“We will describe an answering and recording telephone embodying our invention and then point out the novel features in the appended claims.”It uses a recording on a wax disk to play a message to callers. This probably had a very limited life and never really caught on. That would wait until the invention of magnetic tape for that to happen.
