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.
This file can be generated by Room EQ Wizard (REW) or by other programs. The design program
must be set for a 96 kHz sample rate. The number of filters is limited to a maximum of ten.
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,
...
biquad10,
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. (Note: 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.
