* <a href="https://developer.mozilla.org/en-US/docs/Web/API/AudioContext"
* title="Audio Context @ MDN">Audio Context</a>
* in a suspended state.</p>
*
* <p>In these browser-specific policies, sound will not play until a user
* interaction event (i.e. <code>mousePressed()</code>) explicitly resumes
* the AudioContext, or starts an audio node. This can be accomplished by
* calling <code>start()</code> on a <code>p5.Oscillator</code>,
* <code> play()</code> on a <code>p5.SoundFile</code>, or simply
* <code>userStartAudio()</code>.</p>
*
* <p><code>userStartAudio()</code> starts the AudioContext on a user
* gesture. The default behavior will enable audio on any
* mouseUp or touchEnd event. It can also be placed in a specific
* interaction function, such as <code>mousePressed()</code> as in the
* example below. This method utilizes
* <a href="https://github.com/tambien/StartAudioContext">StartAudioContext
* </a>, a library by Yotam Mann (MIT Licence, 2016).</p>

* @return {Promise} Returns a Promise that resolves when
* the AudioContext state is 'running'

* <p>SoundFile object with a path to a file.</p>

*
* <p>To do something with the sound as soon as it loads
* pass the name of a function as the second parameter.</p>
*
* <p>Only one file path is required. However, audio file formats
* (i.e. mp3, ogg, wav and m4a/aac) are not supported by all
* web browsers. If you want to ensure compatability, instead of a single
* file path, you may include an Array of filepaths, and the browser will
* choose a format that works.</p>
*
* @class p5.SoundFile
* @constructor
* @param {String|Array} path path to a sound file (String). Optionally,
* you may include multiple file formats in
* an array. Alternately, accepts an object
* from the HTML5 File API, or a p5.File.
* @param {Function} [successCallback] Name of a function to call once file loads
* @param {Function} [errorCallback] Name of a function to call if file fails to
* load. This function will receive an error or
* XMLHttpRequest object with information
* about what went wrong.
* @param {Function} [whileLoadingCallback] Name of a function to call while file
* is loading. That function will
* receive progress of the request to
* load the sound file
* (between 0 and 1) as its first
* parameter. This progress
* does not account for the additional
* time needed to decode the audio data.
*
* @example
* <div><code>
* let mySound;
* function preload() {
* soundFormats('mp3', 'ogg');
* mySound = loadSound('assets/doorbell');
* }
*
* function setup() {
* let cnv = createCanvas(100, 100);

* background(220);
* text('tap here to play', 10, 20);

/**
* <p>FFT (Fast Fourier Transform) is an analysis algorithm that
* isolates individual
* <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,

* frequencies so that the delay does not sound as piercing as the
* original source.

* extends p5.Reverb allowing you to recreate the sound of actual physical

/**
* Compressor is an audio effect class that performs dynamics compression
* on an audio input source. This is a very commonly used technique in music
* and sound production. Compression creates an overall louder, richer,
* and fuller sound by lowering the volume of louds and raising that of softs.
* 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.
*
