BiquadFilterNode
The BiquadFilterNode interface of the Web Audio API represents a second-order recursive linear filter, also known as a biquad filter. It is used to implement a variety of common signal processing filters, including lowpass, highpass, bandpass, low-shelf, high-shelf, peaking, notch, and allpass filters. The BiquadFilterNode interface inherits properties and methods from its parent, AudioNode.
A BiquadFilterNode always has exactly one input and one output. The number of channels in the input
The BiquadFilterNode interface provides a set of properties that allow the filter's parameters to be controlled.
The BiquadFilterNode interface also provides a method called getFrequencyResponse, which can be used to obtain the
In summary, the BiquadFilterNode interface is a powerful tool for implementing a wide range of audio effects
