Since my project is now incorporating sound recording I thought I would check out the history of sound recording. The first way people could record music was with the invention of machines like the music box. These were basically mechanized instruments that played interchangeable dimpled cylinders. In 1860 the phonautograph recorded the first human voice. The quality was terrible but in 1877 Thomas Edison invented the phonograph which was the first effective way to record sounds. The phonograph also was capable of playing back recordings whereas the phonautograph could only record. In the early 20's breakthroughs in electronics brought on new discoveries of electrical ways of recording and hearing sound. New microphones, speakers, mixers, and recorders were developed that worked by electric means. With the development of the magnetic tape, recordings could now be precisely edited, and recorded over and over on the same tape. From there quality was improved through things like Dolby noise reduction, hi-fi stereo sound, and surround sound. Now that we are in the digital age, this is the primary means of recording, using computers or digital recorders to edit and record sounds.
