BBE High Definition Sound is the core sound enhancement technology licensed by BBE Sound and featured in the BBE Sonic Maximizer range of professional audio signal processors. Other technologies licensed by BBE Sound into the consumer electronics market either incorporate this core technology or are optimized for best results when used with BBE High Definition Sound.
Because the BBE Sonic Maximizer range of professional audio processors is so popular among music and sound professionals we first highlight the benefits of BBE High Definition Sound in terms of useage by musicians and sound professionals:
- Natural Musical Realism - music has great "live presence". Unlike some "exciter" devices which add fatiguing artificial harmonics to the signal, BBE adds nothing artificial to the signal but instead restructures it to faithfully allow all the detail and nuance to be heard.
- Full Frequency Operation - Highs frequencies are clearer, naturally brilliant and more finely detailed. Lows are tight, well defined and harmonically rich. All from a single processor with easy two-knob adjustment of the BBE process.
- Speech intelligibility - Sound contractors know that vocal intelligibility is paramount to a successful PA installation and client satisfaction. No other audio processor brings natural clarity and crisp definition to the spoken word like BBE does. That's why BBE Sonic Maximizer processors can be found installed in PA systems ranging from the massive network in New York's JFK airport to the thousands of houses of worship around the world.
- Electric and acoustic guitars - have sparkle, clarity and definition. BBE sound processing brings out the harmonic complexity and bite significantly increases cutting power. Each note of a chord becomes more distinct. Brings guitars out of the "mud".
- Keyboards and synthesizers - take on new realism. Percussive and plucked sounds are clear and sharp, chords are rich and full-textured, each note in the chord retains its integrity.
- Electric & acoustic basses - take on that rich, earthy "CD" sound. Five string players love what it does to the "B" string. Extremely tight, punchy bottom end with all the presence, clarity and bite of the top end.
- Vocals - cut through the amplified instrument so you can be heard better. Lyrics of the sound are no longer "buried in the mix".
- Improves effect processing - expands the spatial dimension of stereo reverb and chorus. Whether in an individual instrument rack or across a full mix, BBE makes a dramatic improvement in the quality of effects and neutralizes their tendency to muffle instrument and vocal characteristics.
- Recording studios, home and professional - use BBE on individual tracks, mixdown, and of course in mastering, BBE brings out the full spectrum of sound. Mixes with BBE are fresh and sparkly. BBE gives you enough sparkle to restore instrument clarity or increase vocal intelligibility without appreciably adding level.
- Broadcast clarity - broadcast facilities all over the the world depend on BBE for the best possible transmission quality. From huge operations such as Japan's NHK to local music stations such as Los Angeles' 94.7 The Wave, BBE has become a necessity for modern quality broadcast quality.
Transients and Harmonics: The Color Codes of Sound
To understand how BBE sound processing technology works, consider the characteristics of a loudspeaker and what we expect from one. Among a loudspeaker's most important requirements is the ability to reproduce transients - the brief high-energy bursts at the beginning of sounds. The transients then evolve into harmonics. It is the particular amplitudes and phase relationships of these transients and harmonics which add the unique color and character to each sound.
Varying either the amplitude or the phase of the transients and harmonics within signal causes distortion of the sound's characteristics. By drastically altering the transient response of a sound, it's possible to make a cymbal crash seem like a car crash. Similarly, altering amplitude or phase relationships of the harmonics in a clarinet's tone can make it sound more like a flute, or a French horn like an oboe.
Amplitude and Phase
A loudspeaker's transient response is typically expressed in terms of amplitude response (how quickly it reacts to an incoming signal), with little or no regard to phase response (whether high and low frequencies are reproduced at the proper time). The ability to accurately represent a sound's phase and amplitude define the quality of a loudspeaker's transient and steady - state, or sustained, response.
If a loudspeaker's amplitude response curve were linear, then the relationship between the high and low frequencies would be correct. And if a loudspeaker's phase response curve were linear, then the low and high frequencies would reach the listener's ears in their correct time order. This would result in faithful reproduction of the sound. However, this isn't normally the case.
Why is Live Sound so Pleasing?
When we listen to live music, all of the highs and lows reach our ears in the same relationship to each other as when they were created by the instruments. If this same live music were to be recorded and played back through a loudspeaker system, the loudspeaker would introduce frequency-dependent phase shifting. The inductance of the speaker's voice coil creates a stronger impedance as the signal's frequency increases, resulting in a time delay. Consequently, frequency components with large negative phase shifts (high frequencies) arrive at the listener's ear later than signals undergoing small phase shifts (low frequencies). The resultant signal is distorted in the time domain to the listener's ear. Audio material containing sharp transients (e.g., percussive and plucked sounds such as drums, guitar, piano and harpsichord, etc.) suffers the most from this phenomenon, making it seem unfocused, or mushy.
In order to address these problems inherent in basic loudspeaker design, BBE Sound, Inc. has developed a circuit that has two primary functions. The first adjusts the phase relationships of the low, mid and high frequencies. Since a loudspeaker's natural tendency is to add progressively longer delay times to higher frequencies, the BBE sound processing system adds progressively longer delay times to lower frequencies. This creates a kind of "mirror" curve to the time delay curve created by the speaker, neutralizing its phase distortion.
The second major element in the BBE system is the augmentation of the higher and lower frequencies. Loudspeakers tend to be less efficient in their extreme treble and bass ranges. Most sound-reproducing systems include a circuit for boosting high and low frequencies, showing an accepted awareness of the loudspeaker's efficiency problem. The BBE system, however, provides a dynamic, program-driven augmentation which combines with the phase compensation feature to restore the brilliance and clarity of the original live sound. The result is, as one professional journal phrased it, "The most hearable advance in audio technology since high fidelity itself!"

Simply Amazing....,
By Ryan S. (NY,NY USA) - See all my reviews
Amazon Verified Purchase(What's this?)
This review is from: BBE 882i Sonic Maximizer (Electronics)
The BBE 882i, is simply amazing. It has done more for my setup than anything else I have purchased thus far. I use it with both a Korg Triton Studio 88 key keyboard and a Nuemann tlm 103. The BBE 882i is the second thing in my signal chain (right after my preamp) and the effect on my sound is no less than profound. When used with a Korg Triton Studio keyboard the clarity produced is absolutely stunning( not to say it was bad before, when I bought it new about 4 years back,it was $6,000 us and to this day is still one of the best keyboards on the market) but the BBE 882i makes it sound so much better. When the used with the Neumann 103, once again the clarity produced is amazing (I like the sound it produces better than a u87). I have also used it with much cheaper mics such as the Studio Projects C1 and an Audio Technica 2020 with great results. I would suggest this to anyone who owns a recording studio or has a home studio. One word of advice I would suggest setting all the levels on the 882i to level 6 ( this seems to give the best results with large diaphragm condenser microphones and keyboards).

This is a MUST,

This review is from: BBE 882i Sonic Maximizer (Electronics)
If you record you probably will find use for this. If you go live then this isn't an option! YOU MUST HAVE THIS IN YOUR RACK!!!! this isn't negociable, the improvement is dramatic. Get your bbe maximizer and test it for yourself... once properly adjusted it works miracle on your current sound system. It is so simple to tweek that it wont take more than 5 min.

Just buy it!,
Amazon Verified Purchase(What's this?)
This review is from: BBE 882i Sonic Maximizer (Electronics)
I was nearly deterred by the stupid comments of forumites who cast their dumb and uninformed opinions on this processor. They all said that it was worthless and more useful as a door stop. Ridiculous. This is easily the most important piece of my live sound rack for controlling tone. To summarize what it actually does without science talk, once activated it sounds as though you've MAGICALLY pulled a wad of cotton out of each speaker. A large wad. Anyone who has spent a large amount of time around stereos, PA systems, and live sound rigs without a sonic maximizer is literally stupefied when they hear it work. It is a wonder that it is not bundled with every sound component from the factory. Just buy it. You'll laugh at any competitor who doesn't own one as their sound will be muddy and mottled, while yours is crisp and brilliant.
And damn, for the price here, why wouldn't you?
