The Aphex Aural Exciter has become a standard in the music industry and has been used for years on thousands of albums, movies, broadcast productions, commercials and concerts. The Aural Exciter is now accepted as a unique method to achieve clarity, definition and dimensionality In reproduction of sound. The program material literally “opens up”, possessing more detail and intelligibility, as well as greater apparent frequency and dynamic range. The sound quality Is less subject to degradation through the various generations and transmissions from production to final consumer. The Aphex Aural Exciter achieves these effects by creating a signal composed of frequency dependent phase shift, amplitude dependent harmonics, and mixing this signal with the original. In any natural acoustic environment a listener will hear the primary signal as well as slightly delayed, low level reflections. The phase shifted signal, when mixed back into the original signal, provides a simulation of these reflections, thus generating more natural ambient information. Because the phase shift creates time delays too short to be perceived as an echo or reverb, it is perceived as an increase in the impulse duration. Tests have shown that listener: presented with two signals of equal amplitude and different duration will perceive the signal with longer duration as louder. The Fletcher-Munkm curves show that a listener with normal hearing is most sensitive to changes in the 3 to 5 KHz range. This range is critical for directio perception and intelligibility. Since the Aural Exciter is especially effective in that frequency range, the increase in detail and presence, due to the Aural Exciter, is most dramatic. The only way a listener can differentiate between instruments is through overtones. The louder the fundamental the greater the amount of these overtones. The Aural Exciter generates harmonics ii the same manner. The harmonic structure of each instrument is thus strengthened, allowing it to stand out from the other Instruments. An equalizer can only cut or boost a parti cular section of the audio spectrum. Therefore, if an equalizer is used to brighten the high end, all the noise and distortion will increase also. The high end of the input to the Aural Exciter can be rolled off and the Aural Exciter will generate a brighter, cleaner, more natural high end. Another important difference between the Aural Exciter and other processing equipment is, the Aural Exciter will not induce listener fatigue the way large amounts of equalization or other processing will. In summary, the total effect of the Aural Exciter Is directed towards a sound closer to the original acoustic event. STUDIO USE Aphex processing gives the best results and the greatest flexibility in mixdown applications, but can also be used in tracking and mastering. It is best used in a foldback configuration similar to echo or other external effects, where channel sends can be individually mixed. If separate monitor, echo or cue sends are not available, the mix or stereo busses can be used with reduced flexibility in a "blanketing” effect. It sounds best if the Aural Exciter pan follows the original track pan. This is easiest if two post-fader sends are used to Aural Exciter channels A and B. The send levels must be high enough for proper harmonic generation. The return faders should then be set 10 to 20 dB below the main signal according to the 'desired effect. The effect is addictive, and discretion is advised so that the unit is not overused. SOUND ENFORCEMENT The Aural Exciter can be used with most public address systems in the same manner as studio equipment If separate echo or monitor sends are not available, the unit can be connected in series between the mixer and power amp. In this situation, the Aural Exciter mix would be Introduced into the chain In the mix pot. Aphex processing is especially useful in reverberant halls or halls that have “dead spots'. It will spread the sound more evenly without adding any level to the total mix. The unit’s ability to bring voices and instruments out makes it especially useful for monitor mixing, without increasing feedback. FILM AND VIDEO USE The Aural Exciter has been used on many videotape and motion picture productions to enhance'the soundtrack by recapaturing the live feeling often lost or impaired in location takes . It is unique in its ability to sharpen dialogue, making voices more intelligible while retaining their natural quality. The looping process often required to complete a film or video work is greatly aided by the use of the unit as the Auraf Exciter allows the engineering to tie the loop sound much more closely to the live sound. Theeffect is maintained in transfer from magnetic tape to optical and kept Intact through duplication. Video and film audio are both bandwidth limited and compressed. The Aphex II is especially useful in creating the perception of higher frequencies and greater dynamics, thus bringing more presence and clarity to the final product LEVELS For best results, establishing correct levels is important For that purpose, the dynamic range is internally selectable to maximize signal to noise ratio for any particular reference level. Metering reference level Is selectable for 0 VU +0, +4, +8 dBm or user definable position.
