“modulation tension”; a so-called "envelope follower" continuously scans the
volume of the input signal.
Note: The BitMachine doesn’t recognize the type of audio signal automatically.
For this reason, you should set the input sensitivity roughly with the "gain“ dial.
To do this, use the control LED: With accurate detection of the signal
dynamics, assigning the four small dials to modulation lows is easier and you
can use the full control range.
In envelope mode, the "speed“ dial is used to control the response speed of
the envelope (the display now switches to milliseconds). Lower times result in a
faster response, higher times make the envelope rise (and fall) slower. You
should experiment with the signal according to its complexity. The presets
provided can only point you in a rough direction.
"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.
