Parametric EQ advanced mode
In the PEQ blocks, advanced mode allows each individual filter to be specified by its biquad
coefficients. After pasting in the coefficients, click on the
Process
button for them to take effect.
Parametric EQ file import (REW integration)
Multiple biquads in the PEQ block can be set at once by importing a coefficient file. (Click on the
IMPORT
button.) This file can be generated by Room EQ Wizard (REW) or by other programs. The
design program must be set for a
192 kHz
sample rate for the
C-DSP 8x12
plugin. The number of filters
is limited to a maximum of six.
This example illustrates the correct file format:
biquad1,
b0=0.998191200483864,
b1=-1.9950521500467384,
b2=0.996920046761057,
a1=1.9950521500467384,
a2=-0.9951112472449212,
biquad2,
b0=0.999640139948623,
b1=-1.9981670485581222,
b2=0.9985489719847982,
a1=1.9981670485581222,
a2=-0.9981891119334211,
biquad3,
...
biquad4,
...
biquad5,
b0=1.0010192374642126,
b1=-1.9950555192569264,
b2=0.9940580112181501,
a1=1.995060938714333,
a2=-0.9950718292249559
Note that the last line must not have a comma at the end. If the file has less than ten biquads, then
only that number of biquads will be imported. For example, if importing a file with six biquads, the first
six filters will be set, and the last four will not be changed. (Be careful: if the last line ends with a
comma, that counts as an extra biquad.)
If the file contains more than ten biquads, then an error will be reported and no filters will be changed.
Crossover advanced mode
The
Xover
(crossover) blocks have eight biquads on each output channel. In
Advanced
mode, all eight
biquads need to be specified. After pasting in the coefficients, click on the
Process
button for them to
take effect.
