![]() A lower order frequency may reach the listener’s ear first or perhaps simultaneously with that of a higher frequency. These relationships define a sound's "sound" - When these complex relationships pass through a speaker, the proper order is lost. Research has shown that the information which the listener translates into the recognizable characteristics of a live performance are intimately tied into the complex time and amplitude relationships between the fundamental and harmonic components of a given musical note or sound. These difficulties cause such major phase and amplitude distortion that the sound reproduced by a speaker differs significantly from the sound produced by the original source. Loudspeakers have difficulty dealing with the electronic signals supplied by an amplifier. On the other hand, the BBE "Sonic Maximizer" was designed to be a "correction" device. The BBE process does not generate harmonics and can't create anything that isn'tt in the original material. Technically, it adds harmonic distortion, but it is a very pleasing effect when used in moderation. It can actually generate new high-frequency content for "dull" or "muddy" program material. ![]() They're actually two completely different things.Īphex developed the "Aural Exciter" in the 70's and, as GWA said, it generates new harmonics based upon the audio content in the midrange. ![]() There is a difference between the "aural exciter" process and the BBE "Sonic Maximizer" process. Remember the old speakers with the physically different plains for the tweetes and woofer that was suppose to correct for that? My question is the digital realm does not shift so if using that control, you are then PRE-Planning the shift before it goes out to the real world? But the BBE Maximizer in the hardware form allows for timing shift from between the upper and lower to put them back in phase. There are exiciters that add both odd and even and can be controlled. That adds to the clarity if you use odd harmonics. The exciter adds or enhances or what ever you need the upper range of harmonics based on the lower end. ![]() For us OLD guys it corrects the phasing and that is what removes the muddy sound. Have not used in a while but the maximizer offers phase shifting to correct the timing delay difference between the lower and upper frequencies which shift as the signal is processed and passed through the various pieces of equipment. Note there is a small difference in the "aural exciter" and others like the BBE. ![]()
