MIOAllpass
• Synopsis: First Order Allpass Filter
• Category: Phase EQ, Building Blocks
• Channels: 1
Description:
MIOAllpass provides an adjustable high-order all-pass filter. When the
Coeff
is 0, the filter acts as
a pure single sample delay. As the
Coeff
is adjusted away from 0, the phase shift becomes more
and more non-linear as a function of phase. The MIOAllpass can be used to implement a phase
equalizer and is also useful as a reverb building block.
Parameters:
Coeff
[-1, 1] s
Sets the coefficient of the of the all-pass filter.

MIOAllpassVD
• Synopsis: Variable Delay First Order Allpass Filter
• Category: Phase EQ, Building Blocks
• Channels: 1
Description:
MIOAllpassVD provides an adjustable high-order all-pass filter. When the
Coeff
is 0, the filter acts
as a pure delay, with the delay time set by
Allpass(samp)
. As the
Coeff
is adjusted away from
0, the phase shift becomes more and more non-linear as a function of phase. The MIOAllpassVD
can be used to implement a phase equalizer and is also useful as a reverb building block.
Parameters:
Coeff
[-1, 1] s
Sets the coefficient of the of the all-pass filter.
Allpass(samp)
[0, 255] samps
Sets the delay time of the pure-delay portion of the allpass filter. This parameter is in samples.
