"Reduction" section
Bits
This dial controls the resolution of the audio material. Turning the dial
to the left results in 16-bit quantization (CD quality). The further it is
turned to the right, the lesser the signal dynamic becomes. In
extreme cases (1-bit), there are only "on“ or "off“ states.
At the intermediate levels, you’ll notice an increase in the background
noise and a decrease in the dynamics. For example, 8-bit
quantization will exhibit dynamics of only 48 dB. Quieter points in the
material sound noisy and very quiet points sound "capped“. This
effect is amplified the more you turn the dial to the left until it starts
crackling or "groaning".
Sample rate
The audio material is "down-calculated" with this dial, i.e. the internal
sample rate is reduced. A new separation ratio between old and new
rates is created. In relation to this ratio, a sample from the data
stream will be "dropped“ at the various points.
Note: The two smaller dials from this section are explained under
Modulation.
Tape simulation (plug-in)
Tape simulation offers you the possibility of giving your recordings an
"analog touch" by imitating typical aspects of a tape recording. In a
lot of studios, 1" and 2" tape machines are still used because they
are thought to create a fullness of sound, "warmth" and "saturation"
that contrasts with the more neutral and analytical sound of digital
technology.
There are numerous factors that are decisive for the sound
expressiveness of tape-based recordings. Some of these are:
• Distortions that occur when the tape is played in the saturation
range,
• changes to the frequency response, since recording and playback-
side filter steps prepare the signal. All machines also feature more or
less pronounced peaks in the frequency spectrum, above all in the
bass range (so-called "head bumps"),
