Pre-process recordings
Extend bandwidth
2.2.2 Tape Duplication
The Aural Exciter may be used to "pre-process" recordings to anticipate the
audio degradation in the medium or during subsequent reproduction. Much
of the detail added by the Aural Exciter will survive filtering and distortion
of the reproduction equipment and provide a better quality audio playback.
Audio and Video Cassette duplication are examples of this application.
Broadcasting is another good example.
2.23 Sound Recording
In the recording studio, post production suite or similar environment, post
processing of previously recorded sound tracks can restore lost vibrance and
realism, even to the extent of saving dialogue or sound effects which were
thought to be unusable. Instruments and vocals can be made to stand out in
the mix without substantially increasing the mix levels or using equalization.
2.2.4 Electronic Music
Many electronic instruments are limited by their sampling rate (bandwidth)
and word length (resolution); they can sound lifeless. The Aural Exciter
actually extends bandwidth and adds details making synthesizers, samplers
and drum machines come alive.
2.23 Broadcasting
Broadcast audio is constrained in dynamics and frequency response to fit the
parameters of AM and FM transmission. AM and FM radio, as well as tele
vision audio, all have unique, critical bandwidth and signal level transmis
sion limits. The Type III is especially useful in creating the perception of
higher frequencies and greater dynamics without pre-emphasis distortion or
overmodulation. As a result, the final audio product has more presence and
clarity, with no apparent increase in noise.
