web.IIRFilterNode
The IIRFilterNode interface of the Web Audio API is a audio.AudioNode
which implements a general infinite impulse response (IIR) filter;
type of filter can be used to implement tone control devices
graphic equalizers as well. It lets the parameters of the filter
be specified, so that it can be tuned as needed.

constructorcljs
Constructor.
The IIRFilterNode() constructor of the Web Audio API creates a new web.IIRFilterNode object which an audio.AudioNode processor which implements a general infinite impulse response filter.
Inherits parameters from the audio.AudioNodeOptions dictionary.
\tcontext
\tA reference to an audio.AudioContext.
\toptions
\tOptions are as follows:
\t\tfeedforward: A sequence of feedforward coefficients. \t\tfeedback: A sequence of feedback coefficients.
Unlike other nodes in the Web Audio API, the options passed into the IIR filter upon creation are not optional. The filter needs these values to work and with the vast range of filters available, there is no default.
