*
* <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>

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

* to samples across a brief moment in time. Each value represents

* • <code>FFT.analyze() </code> computes amplitude values along the

* 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

* You can change the bin array length, but it must be a power of 2

/**
* p5.EQ is an audio effect that performs the function of a multiband

* 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

* 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.

* 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.
