Specifications

power button
The power button, located below the metering section, activates or deactiv-
ates the plug-in. When the power button is off, the internal engine and buf-
fers stop running.
wordlength section
These buttons configure the wordlength reduction feature of PSP Xenon.
Whenever truncation would occur, PSP Xenon applies its high quality dither-
ing algorithm to keep the perceived dynamic range as close to the original as
possible. Please see the Requantize section above for more information on
wordlength and dithering.
bits buttons – set the bit depth of the requantizer output. Choose the proper value depending
on the media type.
noise-shp buttons - select which, if any, of the three types of dither noise spectral distribution is
used. As noted in the Requantizing section, each noise shaping curve is based to some extent
on the izophonic curve of the human auditory system, with C being the most faithful curve. If
no noise shaping button is selected, plain white noise with triangular PDF is applied.
leveller knob
This knob controls the threshold of the leveller. Lower values make its action
more obvious. Keep in mind that the time constant of the leveller’s envelope
detector is very slow. In other words, the leveller’s gain reduction will not be
immediately apparent upon the signal exceeding the threshold. Rather, once
the threshold is exceeded, the leveller will gradually apply gain reduction.
The leveller is especially useful for loudness maximization, because it can
greatly reduce pumping artifacts. When the knob is set fully clockwise, the leveller is off.
