Though no trace of a working paleophone was ever found, Cros is remembered by some historians as an early inventor of a sound recording and reproduction machine. [11] The first practical sound recording and reproduction device was the mechanical phonograph cylinder, invented by Thomas Edison in 1877 and patented in 1878.
It is used instead of a push-to-talk button on transmitters or to save storage space on recording devices. On cell phones, it is used to save battery life. Intercom systems that use a speaker in a room as both a speaker and a microphone will often use VOX on the main console to switch the audio direction during a conversation.
Thomas Edison's phonograph becomes the first device to record and reproduce sound. The method is fragile, however, and is prone to damage. [2] 1879: Invention: Thomas Edison invents the first dictation machine, a slightly improved version of his phonograph. [2] 1936: Invention
Shortly after Thomas Edison invented the phonograph, the first device for recording sound, in 1877, he thought that the main use for the new device would be for recording speech in business settings. (Given the low audio frequency of earliest versions of the phonograph, recording music may not have seemed to be a major application.)
1993: Random Access Digital Audio Recorder is the first single box device used for simultaneously recording 24 tracks of digital audio at once, onto hard disk drives. The product, manufactured by Creation Technologies was announced in October 1993 at the AES convention in New York. The first RADAR recorders shipped in August 1994.
Phonograph cylinders (also referred to as Edison cylinders after its creator Thomas Edison) are the earliest commercial medium for recording and reproducing sound.Commonly known simply as "records" in their heyday (c. 1896–1916), a name which has been passed on to their disc-shaped successor, these hollow cylindrical objects have an audio recording engraved on the outside surface which can ...
