Word Length
The output word length of the digital audio data can be varied from 8 bits to 24 bits. Click on the rotary
knob and drag left and right to adjust the value.
PDF (Probability Density Function)
In basic terms, the addition of a dither signal (noise) into the digital audio streams improves linearity in
the reproduction of low-level signals. In other words, as signal level drops (such as in a fade out) dither-
ing helps to maintain a smooth decay. There are three options:
None
No dither signal will be added to the data.
Rectangular
A rectangle shape dither signal will be added to the data.
Triangular
A triangle shape dither signal will be added to the data.
Noise Shaping
Noise shaping is a technique that is used to push quantization noise energy, which in linear digital sys-
tems is normally spread over the whole audio spectrum (0 Hz up to half the sampling frequency), into
higher frequencies where the human ear is less sensitive to its effects. There are three noise shaping
options:

When checked, a narrow colored bar is inserted at the bottom of each input strip
which indicates which card (in a multi-board system) is providing the DSP for the
strip.
