BBE High Definition Sound System is patented by BBEsound, Inc. of the United States. The technology originated in 1985. Now, after several generations of development, BBE technology has been used in The patented technology on power amplifiers has developed into fields such as AV audio-visual, Walkman, radio, CD and now digital audio technology.

BBE technology does not simply enhance high-frequency waves, but advances the delayed high-frequency waves and places them before the fundamental wave. It also uses some enhancement techniques to restore some weakened high-frequency waves. BBE divides the audio signal into three parts: low frequency below 150Hz, medium frequency between 150 and 1200Hz, and high frequency above 1200Hz. BBE technology delays the mid-frequency and low-frequency parts by 2.5 milliseconds and 0.5 milliseconds respectively, leaving the high-frequency part unchanged. As a result, the high-frequency part is relatively advanced in time, so that the overall effect of the phase transition is very flat and linear. BBE uses medium and high frequency signals as its adaptive amplitude compensation reference. By closely monitoring the medium and high frequency signals, the absolute value circuit and its auxiliary circuit, it continuously outputs a signal that reflects the high-order harmonic output. Based on VCA control, it can intelligently automatically adjust the amplitude of high-order harmonics to the optimal state. At the same time, BBE can also be used to restore the phase and amplitude of high-order harmonics. The BBE processor is equipped with a low-frequency amplification circuit, which can amplify low-frequency waves in the range of 50-150HZ in a very linear manner, and can be linearized as the frequency decreases. By increasing the delay, 20Hz sound waves will get a 2.5ms delay relative to higher frequency sound waves. This feature makes the bass very tight and clear, and sounds very natural.

It should be noted that the commonly referred to as BBE technology is just a general term. In fact, BBE technology has different branches for different applications, and BBE is the most basic one. Depending on the application, Also includes: BBE - the most basic algorithm, all other branches are based on BBE BBEMach3Bass - bass boost algorithm, which has a wide range of applications BBEViVA - BBE's 3D effect, suitable for stereo TVs, portable single-sound speakers, etc. BBEMP - Compression compensation algorithm, suitable for MP3, MD and other products that use lossy compressed music formats BBEOptima - Simplified BBE related algorithm, BBE algorithm without adjustment items BBEK3/K1 - Compression/limiting/automatic gain control, suitable for professionals Program recording BBET2/T2R/T 2C /T 2M -BBE phone technology, using BBEMP and BBEK3 technology to achieve high-quality phone calls

Because BBE Sound company has always had very strict quality standards for BBE technology Control, to put it simply, although the licensing fee for BBE technology is very low, it is not that simple to obtain BBE authorization. After the cooperative company applies to BBESound, BBESound will first send people to investigate the cooperative company. Only after the company's strength is recognized will it be authorized by BBE. During the product design process using BBE technology, BBESound will Participate in the design of the sound effects, and only after the final sound quality is approved can the product be marked with the BBESound trademark. It is this rigorous operation method that makes the BBE trademark become an identification mark symbolizing high quality in the audio industry.
