Concert Hall - Lexicon PCM NATIVE Owner's Manual

Concert Hall

The highly acclaimed Lexicon Hall, Concert Hall, and Random Hall reverb algo-
®
rithms have regularly been used by live sound and recording engineers because
of their exceptional ability to reproduce the musical ambience of large, wide,
panoramically wonderful spaces.
This reverb is an updated version of one of Lexicon's oldest algorithms. It was
an essential part of many of the mixes of the late seventies and eighties. It is a
less-dense reverb, allowing it to add lushness to a mix without stepping on the
dry source material. It also has quite noticeable modulation, causing strong pitch
effects at higher settings. The reverb tail has a life of its own, desirable in pop
music, less so in jazz or classical applications.
A hall is the principal venue for classical ensembles, but has proven to be useful
for all types of music. A hall is comparatively large, with wall-to-wall distances
that are typically several tens of meters. Smaller halls may be used for smaller
ensembles. The characteristic sound of a hall includes very low initial reflection
density, with little reflection energy before 60-100 milliseconds. Density buildup is
more gradual, because of the larger distances between reflecting surfaces. Re-
verberation time is somewhat longer as well. Finally, in most halls lower frequen-
cies reverberate longer than higher frequencies.
