p5.Envelope: An Envelope is a series
- * of fades over time. Often used to control an object's
- * output gain level as an "ADSR Envelope" (Attack, Decay,
- * Sustain, Release). Can also modulate other parameters.
- *
p5.Delay: A delay effect with
- * parameters for feedback, delayTime, and lowpass filter.
- *
p5.Filter: Filter the frequency range of a
- * sound.
- *
- *
p5.Reverb: Add reverb to a sound by specifying
- * duration and decay.
userStartAudio: Enable audio in a
- * browser- and user-friendly way.
- *
p5.sound is on GitHub.
- * Download the latest version
- * here.

Returns the Audio Context for this sketch. Useful for users

- *
- *
Some browsers require users to startAudioContext
- * with a user gesture, such as touchStarted in the example below.
It is not only a good practice to give users control over starting
- * audio. This policy is enforced by many web browsers, including iOS and
- * Google Chrome, which create the Web Audio API's
- * Audio Context
- * in a suspended state.
- *
- *
In these browser-specific policies, sound will not play until a user
- * interaction event (i.e. mousePressed()) explicitly resumes
- * the AudioContext, or starts an audio node. This can be accomplished by
- * calling start() on a p5.Oscillator,
- * play() on a p5.SoundFile, or simply
- * userStartAudio().
- *
- *
userStartAudio() 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 mousePressed() as in the
- * example below. This method utilizes
- * StartAudioContext
- * , a library by Yotam Mann (MIT Licence, 2016).
- * @param {Element|Array} [element(s)] This argument can be an Element,
- * Selector String, NodeList, p5.Element,
- * jQuery Element, or an Array of any of those.

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

- *
- * function setup() {

SoundFile object with a path to a file.

- *
To do something with the sound as soon as it loads
- * pass the name of a function as the second parameter.
- *
- *
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.
- *
- * @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
- *
- * let mySound;
- * function preload() {
- * soundFormats('mp3', 'ogg');
- * mySound = loadSound('assets/doorbell');
- * }
- *
- * function setup() {
- * let cnv = createCanvas(100, 100);
- * cnv.mousePressed(canvasPressed);
- * background(220);
- * text('tap here to play', 10, 20);
- * }

Once instantiated, a p5.FFT object can return an array based on
- * two types of analyses: • FFT.waveform() computes

- * to samples across a brief moment in time. Each value represents
- * amplitude of the waveform at that sample of time.
- * • FFT.analyze() computes amplitude values along the

- * value represents amplitude at that slice of the frequency spectrum.
- * Use with getEnergy() to measure amplitude at specific
- * frequencies, or within a range of frequencies.

FFT analyzes a very short snapshot of sound called a sample
- * buffer. It returns an array of amplitude measurements, referred

- * 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

Convolution multiplies any audio input by an "impulse response"
