Once instantiated, a p5.FFT object can return an array based on\n * two types of analyses:
• FFT.waveform() computes\n * amplitude values along the time domain. The array indices correspond\n * to samples across a brief moment in time. Each value represents\n * amplitude of the waveform at that sample of time.
\n * • FFT.analyze() computes amplitude values along the\n * frequency domain. The array indices correspond to frequencies (i.e.\n * pitches), from the lowest to the highest that humans can hear. Each\n * value represents amplitude at that slice of the frequency spectrum.\n * Use with getEnergy() to measure amplitude at specific\n * frequencies, or within a range of frequencies.

FFT analyzes a very short snapshot of sound called a sample\n * buffer. It returns an array of amplitude measurements, referred\n * to as bins. The array is 1024 bins long by default.\n * You can change the bin array length, but it must be a power of 2\n * between 16 and 1024 in order for the FFT algorithm to function\n * correctly.

Use setRange to change the attack/release level.\n * Use setADSR to change attackTime, decayTime, sustainPercent and releaseTime.

Convolution multiplies any audio input by an \"impulse response\"\n * to simulate the dispersion of sound over time. The impulse response is\n * generated from an audio file that you provide.

A phrase is a pattern of musical events over time, i.e.\n * a series of notes and rests.

Phrases must be added to a p5.Part for playback, and\n * each part can play multiple phrases at the same time.\n * For example, one Phrase might be a kick drum, another\n * could be a snare, and another could be the bassline.

\n *\n *

The first parameter is a name so that the phrase can be\n * modified or deleted later. The callback is a a function that\n * this phrase will call at every step—for example it might be\n * called playNote(value){}. The array determines\n * which value is passed into the callback at each step of the\n * phrase.

FFT (Fast Fourier Transform) is an analysis algorithm that\n * isolates individual\n * \n * audio frequencies within a waveform.

\n *\n *

Once instantiated, a p5.FFT object can return an array based on\n * two types of analyses:
• FFT.waveform() computes\n * amplitude values along the time domain. The array indices correspond\n * to samples across a brief moment in time. Each value represents\n * amplitude of the waveform at that sample of time.
\n * • FFT.analyze() computes amplitude values along the\n * frequency domain. The array indices correspond to frequencies (i.e.\n * pitches), from the lowest to the highest that humans can hear. Each\n * value represents amplitude at that slice of the frequency spectrum.\n * Use with getEnergy() to measure amplitude at specific\n * frequencies, or within a range of frequencies.

\n *\n *

FFT analyzes a very short snapshot of sound called a sample\n * buffer. It returns an array of amplitude measurements, referred\n * to as bins. The array is 1024 bins long by default.\n * You can change the bin array length, but it must be a power of 2\n * between 16 and 1024 in order for the FFT algorithm to function\n * correctly. The actual size of the FFT buffer is twice the\n * number of bins, so given a standard sample rate, the buffer is\n * 2048/44100 seconds long.

PeakDetect works in conjunction with p5.FFT to\n * look for onsets in some or all of the frequency spectrum.\n *

\n *

\n * To use p5.PeakDetect, call update in the draw loop\n * and pass in a p5.FFT object.\n *

\n *

\n * You can listen for a specific part of the frequency spectrum by\n * setting the range between freq1 and freq2.\n *

\n *\n *

threshold is the threshold for detecting a peak,\n * scaled between 0 and 1. It is logarithmic, so 0.1 is half as loud\n * as 1.0.

\n *\n *

\n * The update method is meant to be run in the draw loop, and\n * frames determines how many loops must pass before\n * another peak can be detected.\n * For example, if the frameRate() = 60, you could detect the beat of a\n * 120 beat-per-minute song with this equation:\n * framesPerPeak = 60 / (estimatedBPM / 60 );\n *

Only one file path is required. However, audio file formats\n * (i.e. mp3, ogg, wav and m4a/aac) are not supported by all\n * web browsers. If you want to ensure compatability, instead of a single\n * file path, you may include an Array of filepaths, and the browser will\n * choose a format that works.

\n *\n * @class p5.SoundFile\n * @constructor\n * @param {String|Array} path path to a sound file (String). Optionally,\n * you may include multiple file formats in\n * an array. Alternately, accepts an object\n * from the HTML5 File API, or a p5.File.\n * @param {Function} [successCallback] Name of a function to call once file loads\n * @param {Function} [errorCallback] Name of a function to call if file fails to\n * load. This function will receive an error or\n * XMLHttpRequest object with information\n * about what went wrong.\n * @param {Function} [whileLoadingCallback] Name of a function to call while file\n * is loading. That function will\n * receive progress of the request to\n * load the sound file\n * (between 0 and 1) as its first\n * parameter.

Once instantiated, a p5.FFT object can return an array based on\n * two types of analyses:
• FFT.waveform() computes\n * amplitude values along the time domain. The array indices correspond\n * to samples across a brief moment in time. Each value represents\n * amplitude of the waveform at that sample of time.
\n * • FFT.analyze() computes amplitude values along the\n * frequency domain. The array indices correspond to frequencies (i.e.\n * pitches), from the lowest to the highest that humans can hear. Each\n * value represents amplitude at that slice of the frequency spectrum.\n * Use with getEnergy() to measure amplitude at specific\n * frequencies, or within a range of frequencies.

FFT analyzes a very short snapshot of sound called a sample\n * buffer. It returns an array of amplitude measurements, referred\n * to as bins. The array is 1024 bins long by default.\n * You can change the bin array length, but it must be a power of 2\n * between 16 and 1024 in order for the FFT algorithm to function\n * correctly.

PeakDetect works in conjunction with p5.FFT to\n * look for onsets in some or all of the frequency spectrum.\n *

\n *

\n * To use p5.PeakDetect, call update in the draw loop\n * and pass in a p5.FFT object.\n *

\n *

\n * You can listen for a specific part of the frequency spectrum by\n * setting the range between freq1 and freq2.\n *

\n *\n *

threshold is the threshold for detecting a peak,\n * scaled between 0 and 1. It is logarithmic, so 0.1 is half as loud\n * as 1.0.

\n *\n *

\n * The update method is meant to be run in the draw loop, and\n * frames determines how many loops must pass before\n * another peak can be detected.\n * For example, if the frameRate() = 60, you could detect the beat of a\n * 120 beat-per-minute song with this equation:\n * framesPerPeak = 60 / (estimatedBPM / 60 );\n *

Only one file path is required. However, audio file formats\n * (i.e. mp3, ogg, wav and m4a/aac) are not supported by all\n * web browsers. If you want to ensure compatability, instead of a single\n * file path, you may include an Array of filepaths, and the browser will\n * choose a format that works.

\n *\n * @class p5.SoundFile\n * @constructor\n * @param {String|Array} path path to a sound file (String). Optionally,\n * you may include multiple file formats in\n * an array. Alternately, accepts an object\n * from the HTML5 File API, or a p5.File.\n * @param {Function} [successCallback] Name of a function to call once file loads\n * @param {Function} [errorCallback] Name of a function to call if file fails to\n * load. This function will receive an error or\n * XMLHttpRequest object with information\n * about what went wrong.\n * @param {Function} [whileLoadingCallback] Name of a function to call while file\n * is loading. That function will\n * receive progress of the request to\n * load the sound file\n * (between 0 and 1) as its first\n * parameter.

Once instantiated, a p5.FFT object can return an array based on\n * two types of analyses:
• FFT.waveform() computes\n * amplitude values along the time domain. The array indices correspond\n * to samples across a brief moment in time. Each value represents\n * amplitude of the waveform at that sample of time.
\n * • FFT.analyze() computes amplitude values along the\n * frequency domain. The array indices correspond to frequencies (i.e.\n * pitches), from the lowest to the highest that humans can hear. Each\n * value represents amplitude at that slice of the frequency spectrum.\n * Use with getEnergy() to measure amplitude at specific\n * frequencies, or within a range of frequencies.

FFT analyzes a very short snapshot of sound called a sample\n * buffer. It returns an array of amplitude measurements, referred\n * to as bins. The array is 1024 bins long by default.\n * You can change the bin array length, but it must be a power of 2\n * between 16 and 1024 in order for the FFT algorithm to function\n * correctly.

\n *\n *

Convolution multiplies any audio input by an \"impulse response\"\n * to simulate the dispersion of sound over time. The impulse response is\n * generated from an audio file that you provide. One way to\n * generate an impulse response is to pop a balloon in a reverberant space\n * and record the echo. Convolution can also be used to experiment with\n * sound.

threshold is the threshold for detecting a peak,\n * scaled between 0 and 1. It is logarithmic, so 0.1 is half as loud\n * as 1.0.

\n * The update method is meant to be run in the draw loop, and\n * frames determines how many loops must pass before\n * another peak can be detected.\n * For example, if the frameRate() = 60, you could detect the beat of a\n * 120 beat-per-minute song with this equation:\n * framesPerPeak = 60 / (estimatedBPM / 60 );\n *
