 *  <p>FFT (Fast Fourier Transform) is an analysis algorithm that

 *  <a href="https://en.wikipedia.org/wiki/Audio_frequency">
 *  audio frequencies</a> within a waveform.</p>
 *
 *  <p>Once instantiated, a p5.FFT object can return an array based on
 *  two types of analyses: <br> • <code>FFT.waveform()</code> computes
 *  amplitude values along the time domain. The array indices correspond
 *  to samples across a brief moment in time. Each value represents
 *  amplitude of the waveform at that sample of time.<br>
 *  • <code>FFT.analyze() </code> computes amplitude values along the
 *  frequency domain. The array indices correspond to frequencies (i.e.
 *  pitches), from the lowest to the highest that humans can hear. Each
 *  value represents amplitude at that slice of the frequency spectrum.
 *  Use with <code>getEnergy()</code> to measure amplitude at specific
 *  frequencies, or within a range of frequencies. </p>
 *
 *  <p>FFT analyzes a very short snapshot of sound called a sample
 *  buffer. It returns an array of amplitude measurements, referred
 *  to as <code>bins</code>. The array is 1024 bins long by default.
 *  You can change the bin array length, but it must be a power of 2
 *  between 16 and 1024 in order for the FFT algorithm to function
 *  correctly. The actual size of the FFT buffer is twice the
 *  number of bins, so given a standard sample rate, the buffer is
 *  2048/44100 seconds long.</p>

/**
 * 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).

/**
 *  Delay is an echo effect. It processes an existing sound source,
 *  and outputs a delayed version of that sound. The p5.Delay can
 *  produce different effects depending on the delayTime, feedback,
 *  filter, and type. In the example below, a feedback of 0.5 (the
 *  default value) will produce a looping delay that decreases in
 *  volume by 50% each repeat. A filter will cut out the high
 *  frequencies so that the delay does not sound as piercing as the
 *  original source.

/**
 * Compressor is an audio effect class that performs dynamics compression

 * Compression can be used to avoid clipping (sound distortion due to
 * peaks in volume) and is especially useful when many sounds are played
 * at once. Compression can be used on indivudal sound sources in addition
 * to the main output.

 *  <p>PeakDetect works in conjunction with p5.FFT to

 *  </p>
 *  <p>
 *  To use p5.PeakDetect, call <code>update</code> in the draw loop
 *  and pass in a p5.FFT object.
 *  </p>
 *  <p>
 *  You can listen for a specific part of the frequency spectrum by
 *  setting the range between <code>freq1</code> and <code>freq2</code>.
 *  </p>
 *
 *  <p><code>threshold</code> is the threshold for detecting a peak,
 *  scaled between 0 and 1. It is logarithmic, so 0.1 is half as loud
 *  as 1.0.</p>
 *
 *  <p>
 *  The update method is meant to be run in the draw loop, and
 *  <b>frames</b> determines how many loops must pass before
 *  another peak can be detected.
 *  For example, if the frameRate() = 60, you could detect the beat of a
 *  120 beat-per-minute song with this equation:
 *  <code> framesPerPeak = 60 / (estimatedBPM / 60 );</code>
