Tape duplication is often made at high speed, resulting in a dete- rioration of the high frequency spectrum of the copies. By proces- sing the output from the source machine, additional brightness can be added to compensate for deficiencies in the copying system. It may also be necessary to modify the bass end as many high speed systems fail to reproduce the bass end of the spec- trum faithfully. In both applications, the VITALIZER is both effec- tive and simple to set up.

The VITALIZER is perfectly suited for the production of radio jingles, commercials and station idents. Due to the unique proces- sing of the VITALIZER the treated signal will appear louder, closer, brighter and more intelligible than those signals broadcasted without VITALIZER processing. In commercial radio, the VITALIZER can be used to process the entire on-air signal helping the radio station stand out from the competition. The integral STEREO WIDTH expander creates a wider stereo spread for those listeners using a narrow speaker geometry (e. g. car and portable systems).

In live performances or in club installations, the VITALIZER is a powerful ally in maintaining speech intelligibility under difficult conditions. It is also of great benefit in systems designed to play recorded music because the hearing sensation of loudness can be maintained at lower absolute SPLs. This could be particularly beneficial with the introduction of new noise level legislation. On the subjective side, the VITALIZER helps produce a detailed, tight sound, even from indifferent speaker systems giving an improve- ment in perceived audio quality.

As in other areas, the VITALIZER can be used to optimise dialogue, especially when the microphone placement is inadequate (for example when the mic must be kept out of shot). Music sound- tracks benefit in the same way as described for audio-only appli- cations. For most soundtrack producers the enormous ease of use compared with tuning multi-band equalisers means to save a lot of wasted time.

Time-compressed audio can also be treated to restore the lack of timbre. This is particularly valid in the case of vocal narratives as even a relatively small amount of time compression or expansion can dramatically compromise the sound quality.

On the post production work on Spike Lee´s “Malcom X” the voice of Denzel Washington playing Malcolm X was treated with the Vitalizer for dramatical reasons:

“We wanted to make sure that there was a dramatic quality difference between the voice-over and the sync dialog,” Fleischman adds, offering a mixer´s view.“You try to find a balance between two center mics then balance that with whatever you´re using from left-right pair. We then treated it with the SPL Vitalizer, a program equalizer. It brings a lot more presence to the upper end of the spectrum and a very deep low end so that the voice sounds full.” (Mix Magazine)
