THE BLOCKS
Carrier Locut*
Cuts off frequencies lower than the selected frequency on
the Carrier input. The slope of the filter is 12dB/octave.
Range: 10Hz-16kHz.
Carrier Highcut*
Cuts off frequencies higher than the selected frequency on
the Carrier input. The slope of the filter is 12dB/octave.
Range: 10Hz-16kHz.
Out Locut*
Cuts off frequencies lower than the selected frequency on
the output signal. The slope of the filter is 12dB/octave.
Range: 10Hz-16kHz.
Out Highcut*
Cuts off frequencies higher than the selected frequency on
the output signal. The slope of the filter is 12dB/octave.
Range: 10Hz-16kHz.
Mix*
Mixes between direct sound and effect.
In Level*
Controls the input level of the block.
Out Level*
Controls the output level of the Vocoder block.
Ring Mod. External
A Ring Modulator in general is best explained in the
frequency domain: When two different sine wave signals
with frequencies f1 and f2, and dynamic range f1 and f2 are
applied to the inputs of a Ring Modulator, the upper sideband
produces a sine wave with the frequency f1+ f2 and the
dynamic range f1+ f2. The lower sideband produces a sine
wave with the frequency f1 - f2 and the dynamic range f1+f2.
The FireworX performs a generalized Ring Modulator called
quadrature modulator which makes it possible to control the
relationship between the upper and lower sideband. A fifty
fifty mix of the upper and lower sideband equals the sound
of a traditional ring modulator.
Note that the dynamic range of the sideband outputs is the
sum of the dynamic ranges of the two inputs, so
compression of one or both inputs is recommended. This can
be done by using the build in Carrier AGC (Automatic Gain
Control). The parameters available in the Modifier Matrix
are marked with an asterisk*.
input, Mono out algorithms. They both require a Carrier on
one input channel and a Control (Vocal) on the other channel
input.
Vocoder
A Vocoder in general is a two-input, one-output device that
detects the spectral envelope of the Control (Vocal) input and
filters the signal of the Carrier input through a filter
controlled by that spectral envelope. To maintain a constant
output level the Vocoder contains a gated AGC (Automatic
Gain Control) on the Carrier input. The parameters available
in the Modifier Matrix are marked with an asterisk*.
VOCODER
Carrier Chnl
The Carrier channel parameter swaps the Left/Right inputs
Vox/Carrier connection.
Carrier AGC
Switches the Automatic Gain Control on the Carrier input
on/off.
AGC Maxgain
Sets maximum gain that the AGC will add to the Carrier
input signal.
Output Pan*
Controls the panning of the Vocoder output.
Vox Locut*
Cuts off frequencies lower than the selected frequency on the
Vocal input. The slope of the filter is 12dB/octave.
Range: 10Hz-16kHz.
Vox Highcut*
Cuts off frequencies higher than the selected frequency on
the Vocal input. The slope of the filter is 12dB/octave.
Range: 10Hz-16kHz.
