Filter Design Using Second-Order Peaking and Shelving Sections

  title={Filter Design Using Second-Order Peaking and Shelving Sections},
  author={Jonathan S. Abel and David P. Berners},
A method for designing audio lter s is developed based on the observation that second-order peaking and shelving lters can be made nearly self-similar on a log magnitude scale with respect to peak and shelf gain changes. By cascading such second-order sections, lter s are formed which may be t to dB magnitude characteristics via linear least-squares techniques. A graphic equalizer interpolating prescribed band gains is presented, along with a lter minimizing the Barkweighted mean square dB…

Graphic Equalizer Design with Symmetric Biquad Filters

A novel graphic equalizer design comprised of a single second-order section per band is proposed, where the band filters have a symmetric shape about their center frequency in the entire audio range.

Third-Octave and Bark Graphic-Equalizer Design with Symmetric Band Filters

This work proposes graphic equalizer designs with third-octave and Bark frequency divisions using symmetric band filters with a prescribed Nyquist gain to reduce approximation errors and applies a recently proposed neural gain control in which the filter gains are predicted with a multilayer perceptron having two hidden layers.

An Automatic Design Procedure for Low-order IIR Parametric Equalizers

An optimization procedure is presented for the automatic design of a low-order equalizer using parametric infinite impulse response (IIR) filters, specifically second-order peaking filters and first-order shelving filters.

Accurate Cascade Graphic Equalizer

The proposed cascade graphic equalizer, which uses band filters whose interaction with the two neighboring filters at their center frequency is exactly controlled, is compared with previous designs and is shown to be the most accurate one.

This paper proposes an efficient way of computing the target response without sacrificing the approximation accuracy called Linear Interpolation with Constant Segments (LICS), which reduces the computing time of thetarget response by 55% and has an intrinsic parallel structure.

The quest for the best graphic equalizer

This paper extends the design method for the case of third-octave bands, showing how to choose the parameters to obtain good accuracy and keeps the approximation error below 1 dB using only a single second-order IIR filter section per band.


The design of graphic equalizers has been investigated for decades, but only recently fitting the magnitude response closely enough to the control points has become possible. This paper reviews the


The reverberation time is one of the most prominent acoustical qualities of a physical room. Therefore, it is crucial that artificial reverberation algorithms match a specified target reverberation

Lightweight and Interpretable Neural Modeling of an Audio Distortion Effect Using Hyperconditioned Differentiable Biquads

This work extends trainable infinite impulse response (IIR) filters to the hyperconditioned case, in which a transformation is learned to directly map external parameters of the distortion effect to its internal filter and gain parameters, along with activations necessary to ensure filter stability.
