【 Weak current College 】 what is BBE is the sound quality of the King? (2)---Power By 【 China power house network 】

Use MP processing technology extended MP3 MP3 file contains the frequency range to acceptable quality copy sound required minimum signal, only 1/20 of acoustic information, the remaining signal is lost. Compressed file size of another strategy is to reduce the frequency range. Obviously, the MP3 music CD of high frequency signal ratio. 　　The digital compression of audio signals (including WMA) all have this problem. 　　Frequency response: MP3 MP3 frequency response to Sudden Cut-off at relatively low frequencies (cut-off frequency varies): frequency relatively low at the time of the sudden closing (closing rate is not fixed, unchanging) BBE MP treatment could restore the harmonic band; and, as shown in the following figure, with 48 KHz and 96 KHz sampling frequency of too technical, it also can be high-frequency bandwidth up to 24 KHz or 48 KHz. MP3 frequency expansion process: used by MP MP processing technology extended MP3 frequency
Generated harmonics by MP process: MP technology produces harmonics
High frequency expanded by MP process: MP technology extended high-frequency band after
The following figure shows the Diana · Clar singing "I remember you" part of the spectrum, where you can see the BBE MP processing technology. The first picture indicates that 16 KHz frequency in the following test audio, 32 kHz sampling frequency down original CD you can clear the high frequency components. If the second picture shows, you can use BBE MP processing technology to reproduce frequencies restricted test audio 16KHz more harmonic (each beat the beginning of the effect is obvious). The second picture of the central part is 6 KHz band generated KHz-8 harmonic, harmonic frequency number 16KHz, subordination.

32 KHz to 48 KHz sampling frequency resampling can be seen from the following diagram BE MP processing results: MP processing regeneration frequency in 16 KHz and above all signals, resulting in high frequency extension to 24 KHz (this frequency and even raise in the acoustic CD 22 KHz frequency cap). From the diagram also shows that the frequency response of the soundtrack CD is copied exactly.
Diana · Clar singing "I remember you"
32 KHz to 48 KHz sampling frequency BBE MP technology processing effects, this kind of technology and similar MP3 PRO decoding technology. The difference is: MP3 PRO decoder only encoded audio, MP processing technology to MP3 and MP3 PRO Audio. In addition, MP technology also applies to all types of digital audio formats such as WMA and AAC.
As noted above, BBE technology is United States BBESound company launched in 1985 to significantly improve the sound quality of a sound-enhanced processing technology. 　　This technology in Europe, the United States and Japan have already successfully applied to the radio and television, sound recording industry, professional audio engineering and household, car audio, and other fields, and is widely recognized. 　　That's why this technology will gradually enter into the field to MP3?, there is only one reason: the fierce market competition. You can see a characteristic is, now use BBE sound effects are all SigmaTel chip MP3 solutions.
　　
Why use Philips chip products does not use BBE? Giants not better?
　　
The reason is: integrated DSP/DAC, Philips Philips > > Telchips Sigmatel and don't care about, since he is already a sound first programme, why can't they get a set of audio technology. This is not like some of the domestic manufacturers of various broadcasters, as a veteran audio manufacturer, manufacture chip itself, if you want to make this kind of thing, the choice is Philips.
　　
Philips in MP3 on hand, the combined application of Philips chip best IRIVER, Xtreme3D sound technology has been developed.COWON can rely on our own precision of style to counteract SigmaTel chip, but SigmaTel did not develop your own sound technology, COWON what reversal to such disadvantages, the answer is simple: BBE sound! before CW100, COWON CW200, work is already a very CW300 do feature works, but the effect is really good, when Korea largest brand MPIO, IAUDIO, IRIVER tripod, two are Philips. Only the COWON is to SigmaTel a path through. However the majority of users, top like still aircraft huashanzhi, IRIVER has come up with new sound effects. In this case, the IAudio finally took out BBE unlocks the secrets--! BBE Sonic Maximizer plug-in software effects are meant to sound signal for various effects processing programs, such as reverb, chorus, distortion, chrome, etc. Current music production software available soft effects plug-ins, there are two types, one for DirectX plug-ins, to almost all the audio processing software is called, but the live performance is not satisfactory; VST plug-in, only a few audio processing software can be used, but the excellent performance of the former. All software effects plug-in for VST plug-ins in the majority.

BBE Sound company not only provides the technology and hardware products to professional musicians, they also developed a reputable BBE Sonic Maximizer signal processor new plug-in for VST and Direct X, users do not need to directly capture a digital signal, you can directly use the BBE Sonic Maximizer plug-in. It uses the BBE's fourth-generation processors, and BBE
Hardware product in use of 482 and Sonic Maximizer processor same 882. This can be used for a variety of compatible Direct X and VST plug-ins for PC and Mac audio software. Whether it is a multi-track audio recording or sampling (or even mix), BBE Sonic Maximizer can do. BBE Sonic Maximizer plug-in can be used for a variety of host software did better compatibility, compared with
Name the enthusiasts there are some commonly used: Steinberg Cubase, VST and SL
Type: integrated music production platform Steinberg Cubase VST is a famous music production software, and domestic music widely adopted digital music platform Cakewalk compared to Cubase VST series of function appear. While Cubase VST is not on the use of Cakewalk so convenient, but because of the high-performance multitrack audio processing, real-time effects inserts, and numerous third-party software developers to provide compatibility with the standard soft VSTi audio sources, these are as many foreign music producer of second choice. In addition to ASIO, Steinberg also proposed raising the VSTi soft sound source performance standards and enable software audio effects to real-time VST plug-in specification work. 　　Because of these technical details are made public, so third-party software developers to Cubase VST platform provides a steady stream of new colors and new features. Bias Peak

Acid is a set of background music production software, is to repeat play-based music production tools. It features unlimited cycling track (depending on system memory size), automatic control repeating the beat and rhythm sound tecnologies, real-time control, support 16-bit and 24-bit format of music, but also supports DirectX bolted and time music effect and cannot duplicate music and so on. Music can be in WAV or digital audio formats directly output, new versions or even directly including libraries and supports MP3, WMA, RealMedia G2 format output. 　　Acid also compatible CD Architect and direct-to-digital music format, which can be used as audio editing, producing and burning tool. Syntrillium Cool Edit Pro
Type: digital music editor and MP3 creation software this is probably the most music lovers love to use a software, website-related tutorials and more. Many people put Cool Edit described as audio "painting" program. You can use sound to "redraw" system: part of the pitch, songs, sounds, strings, vibrato, noise or adjust silence. But it also provides a variety of special effects to spice up your work: enlarge, reduce noise, compression, extension, ECHO, distortion, delay, etc. You can work on multiple files, easily in several files to cut, paste, merge, overlap sound operations. Use it to generate sound has: Noise, bass, mute, phone signal, etc. The software also includes a CD player. 　　Other features include: support for the optional plug-ins, crash recovery; support for multiple files; automatic silence detection and deletion; automatic beat find; recording, etc. Cakewalk SONAR
Type: powerful MIDI and digital music tools software Cakewalk family, is one of the most familiar of the sequencer software, hardware sequencer on the verge of elimination of edge largely because of its appearance. He is the MIDI music production in one easy software. Starting from version 4.0, Cakewalk joined the audio processing features, making it a simple sequencer software towards a professional MIDI and audio workstation. Oh, the family first is BBE effects tools! 1, Cakewalk BBE_Sonic_Maximizer woofer sound mixer

Oh, this can be very expensive, not just the beginning. 　　Moreover, the BBE Sonic Maximizer will also enable and MOTU and Logic Audio compatible so that mainstream music production software is basically covers. MP3 and BBE hardware at present, the United States, Japan has a number of companies has launched the second generation of BBE chip. In our common chip with EXAR Corporation of United States and Japan XR1071 XR1075, Roma (ROHM) company BA3884S, Japan JRC company M2178, etc. At present, China's market to see AV amplifier and color TV, many products for cost reasons, the first generation of chips, such as M2150D BBE. Second-generation BBE chips than the first generation to superior, sound better. The first generation of products is to use a switch to force control is parsed, although you can obviously increase the music signal analysis and definition, but because the compensation is too rough and the music signal is easy to produce balance disorders, and less than ideal. 　　Second generation products in technical performance indicators has been greatly improved and increased resolution force control and low-profile regulates potentiometer, according to the specific use to adjust the appropriate compensation increases, therefore, the second generation chips than the first generation in audio signal processing, can make the sound more true to nature, a better balance. 　　Some people might think I'm here is to get a bunch of useless things, because it seems this and far away from the more MP3 because MP3 so far are resolved using the software, hardware, what's the use? but I'd like to list the hardware, because the development trend, which could be built into the MP3. 　　How to develop BBE? or mystery. One possible, update technology and algorithms, so, BBE, completed its historical mission, but in the history of digital music, we cannot forget that once existed a historical stage. To some extent, it can be said, and from apes to people that stood on the historic process can do. Because people are not simply consider the characteristics of the timbre and sound quality, but the pursuit of perfection purity, restore natural sound. At the same time, the pursuit and not depend on how many number of surround speakers to complete restore of the sound field, and is used to BBE as representative of advanced digital technology, will already be covered range features back to restore it. 　　To replace the BBE's new technology will inevitably be thinking along the continues to fundamentally change our present some of the flaws inherent BBE, to join the number sign, in a wider range of players to be more accurate to restore, and oh so brought more music. Another possibility, BBE technology as a standard for the introduction of a wide range of MP3. Methods are 2 types of manufacturers a lot into the BBE authorized, but in a short time, this seemed to still have some difficulties, because the BBE itself can also have so much energy to invest in a large number of manufacturers of so many design, European and American manufacturers have not had access to a list of BBE website. In fact this is easily one of the things that the front BBE hardware chip, we can see, the miniaturization has been making great strides in the development, in the foreseeable future, is likely to BBE authorized chip direct implantation of the circuit to MP3, MP3 software simulation is very good, but now there is no specialized BBEMP3 solutions, hardware BBE solution should be able to obtain better results. MethodBis, Philips chip still occupies a high-end, other chipset design is it possible to direct and BBE sound, directly in MP3 chip are placed in the BBE part of line, so that on the one hand, these manufacturers DPU will direct access to sound upgrade, on the other hand on BBE Sound can eliminate a large number of identification and design time, you can directly check the DPU. As a normal user, the above conjecture is a fanciful-imagine that these issues should belong to the DPU manufacturers, manufacturers of MP3 and BBE company. As an ordinary user, we are concerned with only one thing, it's more of the music, and oh so much more realistic sound effects. 　　I think this is BBE Sound development of the original purpose of this technical-technological progress is to give people a better life, not just to prove that technology. So let us put on headphones, to experience the BBE brings us the wonderful music.
