The History Of Dolby Audio
These days, Dolby is a household name. The infamous "DD" symbol can be found in almost every piece of modern audio equipment out there. This includes gaming consoles, HDTV, Home Theaters, both at home and car stereos, cinemas, and personal computers. It all began in 1949 when a man named Ray Dolby went to work for Ampex Corporation part-time, while still in high school. He worked in a variety of companies in correlation with audio instrumentation. He continued working for Ampex while attending college at Stanford University. During this period, breaks to join a small team of Ampex engineers who were determined to invent the first videotape recorder. Dolby focused on electronic aspects of the project. The group has achieved with the introduction of this new technology in 1956. Ampex later sold its first video recorder for $ 50,000. Dolby graduated from Stanford in 1957 and received a Marshall Scholarship at the University of Cambridge, England. He studied at Cambridge for 6 years, earning a doctorate in physics. In 1965, Ray Dolby has started his own company, Dolby Laboratories, Inc. Its first product of this new and innovative company was identified as Dolby A-type Enoise reduction. It significantly reduced the amount of background noise or hiss in professional tape recording without jeopardizing the original content of the material being recorded. This was the beginning of many new Dolby would make in the complex world of audio compression and expansion. Ray Dolby developed an ingenious method of noise reduction by separating the softest strong signals, then simply not processing the strongest signals. Then divide the spectrum into different bands to avoid contradictions or pumping, therefore generating white noise. This method must be integrated into many aspects of society rapidly growing fascination with electronic entertainment. At first, consumers are not satisfied with ordinary radio players and monkey with the 'plate' cassette issued. Everyone wanted to hear music in stereo. This new sound also found its way into the cinema. Dolby sound made its debut in the original recording of Star Wars, and continues to revolutionize the experience of the public today. The sound is even more spectacular and more natural at the same time. Due to this technology, even video games are more realistic, the sounds are more powerful because they not only heard but also felt. The sound is so tangible it is as if fantasy has in fact become reality. More people are staying home instead of going to the movies since its introduction in Dolby Surround Sound System Home Theater. Recent advances include Dolby 5.1, 6.1, 7.1 and 9.1 (that's right, nine full-range channels), Dolby Digital Surround EX, Dolby SR, Dolby TrueHD, and many others. It is obvious that Dolby is the current "King of Sound" and most likely will for generations to come.
