Parametric EQ advanced mode
In the parametric EQ 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 parametric EQ 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
48 kHz
sample rate if using the
C-DSP 6x8
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 six biquads,
then only that number of biquads will be imported. For example, if importing a file with four
biquads, the first four filters will be set, and the last two 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 six biquads, then an error will be reported and no filters will be
changed.
