/**
* p5.EQ is an audio effect that performs the function of a multiband
* audio equalizer. Equalization is used to adjust the balance of
* frequency compoenents of an audio signal. This process is commonly used
* in sound production and recording to change the waveform before it reaches
* a sound output device. EQ can also be used as an audio effect to create
* interesting distortions by filtering out parts of the spectrum. p5.EQ is
* built using a chain of Web Audio Biquad Filter Nodes and can be
* instantiated with 3 or 8 bands. Bands can be added or removed from
* the EQ by directly modifying p5.EQ.bands (the array that stores filters).
