Hearing good sound from an artificial source is not solely based on a listener's subjective criteria. A sound that is distinct and captivating is also a product of high definition or high-def (HD) technology. Though the term "HD" is often used to refer to "high fidelity" or hi-fi, these two concepts are not synonymous.
With its history dating back to the birth of the Williamson amplifier in 1947, hi-fi sound denotes high-quality stereo equipment. On the other hand, HD is fueled by Intel's chipset innovation that contributes to high-quality digital audio.
Such sound technology generates a computer-powered environment where a listener can manipulate audio software programs and hardware parts to produce the kind of sound or music based on individual preferences. External gadgets such as microphones, headphones, and/or speakers help facilitate the experience for those at home.
However, the HD sound is described as an approximation or a modified version of the original sound source. Thus, it may not be as distinct as that of a hi-fi stereo's. Nevertheless, the HD sound has become a key feature in other A-V technologies, including various digital, broadcast, and/or mobile formats such as television, radio, compact discs, MP3s, and DVDs, among others.
