In live performance or in club installations, the S

TEREO

V

ITALIZER

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 illusion 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 S

TEREO

V

ITALIZER

helps produce

a detailed, tight sound, even from indifferent speaker systems giving an

improvement in perceived audio quality.

The S

TEREO

V

ITALIZER

can be of great value when mixing under time-pres-

sure. You can almost leave the onboard EQs flat and create the FOH sound

with the S

TEREO

V

ITALIZER

in the master inserts.

As in other areas, the S

TEREO

V

ITALIZER

can be used to sharpen and enri-

chen 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 S

TEREO

V

ITALIZER

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," 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 psychoacoustic 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."
