TUBE VITALIZER
3. Tape duplication is often made at high speed resulting in a
deterioration of the high frequency spectrum of the copies. By
processing 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
spectrum faithfully. In both areas, the Tube Vitalizer is both effec-
tive and simple to set up.
4. The Tube Vitalizer is perfectly suited to the production of
radio jingles, commercials and station idents. Because of the
psychoacoustic nature of the processing, the treated signal will
appear louder, closer, brighter and more intelligible than
whatever was played immediately beforehand, thus creating a
powerful impact. In commercial radio, the Tube Vitalizer can be
used to process the entire on-air signal helping the radio station
to stand out from the competition. The Tube Vitalizer can also be
used on feature-films to get a sound closer to the sometimes
heavily processed commercials. In digital audio broadcast (DAB)
the Tube Vitalizer can make a significant contribution to the
sound quality prior to MPEG coding.
5. As in other areas, the Tube Vitalizer can be used to sharpen
and enrichen dialogue, even when the microphone placement is
less than optimum as is often the case when filming due to the
need to keep the mic out of shot. Music soundtracks benefit in the
ways already described for audio-only applications and the fact
that the Tube Vitalizer is so quick to set up can save a lot of wasted
time spent tuning multi-band equalizers.
Time-compressed audio can also be treated to restore the lack
of timbre so often caused by such intensive processing. 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” movie
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. We treated it with the SPL Vitalizer. 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
