Vitalizer on ‘Malcom X’

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
