Talking about Distortion

The distortion is one feared dreadfully the repugnant words and expressions, are probably as a result of its negative significance. Since, on the electroacoustical product, the distortion has been an important indicator. But to the fan, the distorted real sense in? When a signal after the transmission, or after enlarges, in the theory must maintain with the original signal complete invariable is impossible, therefore, looked from the technical angle, the people always hoped its degree of distortion is smaller is better. But the recent years major part senior fan could agree, in listened to the feeling, degree of distortion this target actually could not reflect equipment's good sound degree effectively. If just now has said that since the signal cannot maintain after the transmission or the enlargement with the original signal is completely same, during presents certainly some changes, what is this change? Nothing else but “adds many” and “the reduction” roughly. “the reduction” this concept is easy to understand that was the original signal has lost some things in the transmission or the enlargement process. As for “added many” has the complex content, simply speaking, was in the transmission or the enlargement process, grew some both stems from the original signal and to be different with the original signal the thing. Because these are do not have originally, therefore also can only be the distorted partial content. in listens to the feeling, this kind of derivative unexpectedly will sometimes have the mysterious role, for example, some addition's overtone, played likely the monosodium glutamate function obviously, will like the human will think that added the sound music. Also like microphone effect (microphonic) provided some fans to serve as the tuning one effective measure. Even the phase-shift (Phase Shift), this one sounds not to look like the good thing, may also beautify ingeniously by the use the timbre. Advances the drive effect in the recording process to cause the bass impulse strength greatly to be more solid, has utilized phase-shift this thing. Therefore has one school take to listen finally as the choices, yells the distortion not to hurt the essentials, if because changes into the distortion “the beautification”, or “the monosodium glutamate”, believed that the people to it resistance will be the reductions greatly, but another school mainly will be engineer, actually loudly said: “the digit wins in the convincing argument” (numbers don't lie). Such argument, time consuming, actually who is who must? Here, we do not use fan this concept first, because the average person will possibly favor in thought that the fan will be the odd person who some will overstate, what person can the above argument have the most tremendous influence to? The answer is the human who likes the sound, this was also English Audiophile, the acoustic amateur.
