BBE actually not a new topic, because if you played before this sound, AV system, then definitely get some idea of its. BBE Sound Company in the presentation,
nba jerseys, we learned that BBE technology originated in 1985, and now, BBE technology through several generations of development, has been applied to power amplifier from the original patented technology developed above to the audio from the AV, Walkman, radio , CD and now digital audio technology and other fields. As has been the BBE Sound BBE technology has a very strict quality control, simply, although the BBE technology licensing fees are very low, but want to get the authorization BBE is not so simple. In the cooperative company upon application to the BBE Sound, BBE Sound will be sent first to investigate the cooperative company, the company's strength has been recognized only after authorization by BBE, BBE technologies in products used in the design process, BBE Sound the company will participate in on the audio part of the design to be recognized in the final sound quality, the products can raise the trademarks of BBE Sound. This is also a strict mode of operation, so that BBE trademark as a symbol of superior quality audio industry identification. But unfortunately, due to China on intellectual property rights do not trust, BBE Sound of Chinese enterprises is not yet an algorithm for direct authorization, therefore, at present most of the enterprises in China are third countries through the purchase of chips by BBE Sound's indirect authorization.
Here, we feel that we seem very close from the BBE technology, but very far away. Because ordinary household electrical appliances in China, you can get very little can be said BBE authorized. So no one went to its high-profile publicity. The people who understand the technology, but also rarely have the opportunity to truly experience the BBE technology. BBE technology to lower it do? Before we start the detailed description, please click the following recording lyrics, since I do not have too much professional recording equipment,
cheap minesota twins jerseys, following the recording of a very common use of AC97 sound card, a few of the MP3 decoder chip with the same players, as well as a rather distinctive music:
free download BBE's Sounds: source.wav (1.65M)
BBE processing Download: BBE.wav (2.54M)
SRS treatment Download: SRS.wav (1.9M)
should be obvious from the above lyrics can feel the BBE technology for improved sound quality to bring the whole of the original sound broad range seems a lot more than once high level of bass has become very clear that this experience brought about by the traditional EQ effect is significantly different. BBE in the end that which method to improve the quality of it?
should be noted that the BBE technology is usually only a general term,
dwyane wade jerseys, in fact, BBE technology for different applications in different branches of the time, and a BBE is the most basic , depending on the application of different, but also includes:
BBE ; - the most basic algorithm, all other branches are built on the basis of BBE's
BBE Mach3Bass - bass boost algorithm, application broader
BBE ViVA - BBE, 3D effect, suitable for stereo TV, portable sound reproducing monomer other
BBE MP - compression compensation algorithm for MP3, MD and other use loss of compressed music format products
BBE Optima - BBE simplified correlation algorithm to adjust the items in addition to BBE algorithm
BBE K3/K1 - compression / limit / automatic gain control, apply to professional programs recorded
; BBE T2/T2R/T2C/T2M - BBE phone technology, the integrated use of BBE MP and BBE K3 technology to achieve high quality results
phone call in the end it is what BBE effect? In fact, the effect is not known if the BBE is very accurate, because the starting point so that the final result from its point of view, BBE technology is the hope that in ordinary electronic equipment (amplifier) to restore a more realistic sound quality. We all know that music down signal from the acquisition has been out of the speakers play back the process, the audio signal may have experienced tens to hundreds of electronic components, electronic components, especially those with an inductance capacitance and the Yang Zhi device will occurrence of the audio signal phase shift small, this shift will usually be more high-frequency signals to reach our ears later, and since the auditory characteristics of the human ear, and feel the music has become more ambiguous uncertainty, and not to went to the site that accurate positioning of the instrument. So some of the professional speaker tweeter placed it closer to the listener. The BBE technology for audio signals will be offset to compensate for this part, therefore, sound, BBE treated with music, more clearly.
In addition, a variety of amplifier performance and the transistor, the characteristics of power caused some moments Lai Buji larger music signal is amplified, causing signal distortion, such a result would music not to sound shocked, as shown:
signal amplification as an instant after the signal distortion caused by delay compensation signal
BBE following is drawn out by the computer above the audio spectrum of several tests, it is obvious that the above two points.
test Audio - Audio Source Audio
test-BBE + BBE MP
test the audio-SRS
BBE Mach3Bass is based on BBE above, the algorithm used to improve low-frequency capability, which is different from the general increase EQ simple way, because through some error correction, so it is in enhancing the low frequency, while other frequencies will not make a sense, in particular, IF (vocal) attenuation.
BBE MP algorithm for those of us that play MP3 are often people who are very important because it is to make up for the birth of such lossy compression (including MP3, MD, OGG,
minesota twins jerseys, WMA, etc.) losses. Typically, this type of music compression algorithms discard some of relatively weak signal strength, because in hearing theory, that part of the human ear can not hear the audio. However, in practice, that part of the voice may include some details of the finishing touch. Therefore, this part of the compensation after joining the music,
lebron james jerseys, will make people feel more delicate. Spectra from the above that is obvious to see on the BBE-MP treatment after the music contains more details.
BBE ViVA are used in stereo systems, many of the 3D algorithm through hybrid, offset left and right channels in a specific frequency and giving an illusory sense of space. However, this approach roughly the same time a large part of the expense of sound in the central auditory system (usually vocals), this result provides a 3D effect is the same time, the expense of a lot of sound quality. The BBE ViVA was developed for this problem out of the algorithm.
BBE may say the advantage of so many,
kobe bryant jerseys, you have become impatient, while indeed, the BBE's very strict eligibility requirements for admission, so it is difficult to popularize BBE type of device to see the sight, but not long ago I saw an MP3 player, iAudio's even with the BBE sound, so you can see that digital products are now also began to notice the charm of BBE. I believe that with the improvement of the visibility of BBE, there will be more and more products appear with BBE sound.
