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

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

+ * + *

Once instantiated, a p5.FFT object can return an array based on + * two types of analyses:
• FFT.waveform() 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.
+ * • FFT.analyze() 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 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 + * to as bins. 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.

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

The first parameter is a name so that the phrase can be + * modified or deleted later.

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

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

+ * + *

Once instantiated, a p5.FFT object can return an array based on + * two types of analyses:
• FFT.waveform() 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.
+ * • FFT.analyze() 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 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 + * to as bins. 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.

p5.Signal is a constant audio-rate signal used by p5.Oscillator - * and p5.Envelope for modulation math.

- * - *

This is necessary because Web Audio is processed on a seprate clock. - * For example, the p5 draw loop runs about 60 times per second. But - * the audio clock must process samples 44100 times per second. If we - * want to add a value to each of those samples, we can't do it in the - * draw loop, but we can do it by adding a constant-rate audio signal.This class mostly functions behind the scenes in p5.sound, and returns - * a Tone.Signal from the Tone.js library by Yotam Mann. - * If you want to work directly with audio signals for modular - * synthesis, check out - * tone.js.

- * - * @class p5.Signal - * @constructor - * @return {Tone.Signal} A Signal object from the Tone.js library - * @example - *
- * function setup() { - * carrier = new p5.Oscillator('sine'); - * carrier.amp(1); // set amplitude - * carrier.freq(220); // set frequency - * carrier.start(); // start oscillating - * - * modulator = new p5.Oscillator('sawtooth'); - * modulator.disconnect(); - * modulator.amp(1); - * modulator.freq(4); - * modulator.start(); - * - * // Modulator's default amplitude range is -1 to 1. - * // Multiply it by -200, so the range is -200 to 200 - * // then add 220 so the range is 20 to 420 - * carrier.freq( modulator.mult(-200).add(220) ); - * } - *

p5.Signal is a constant audio-rate signal used by p5.Oscillator + * and p5.Envelope for modulation math.

+ * + *

This is necessary because Web Audio is processed on a seprate clock. + * For example, the p5 draw loop runs about 60 times per second. But + * the audio clock must process samples 44100 times per second. If we + * want to add a value to each of those samples, we can't do it in the + * draw loop, but we can do it by adding a constant-rate audio signal.This class mostly functions behind the scenes in p5.sound, and returns + * a Tone.Signal from the Tone.js library by Yotam Mann. + * If you want to work directly with audio signals for modular + * synthesis, check out + * tone.js.

+ * + * @class p5.Signal + * @constructor + * @return {Tone.Signal} A Signal object from the Tone.js library + * @example + *
+ * function setup() { + * carrier = new p5.Oscillator('sine'); + * carrier.amp(1); // set amplitude + * carrier.freq(220); // set frequency + * carrier.start(); // start oscillating + * + * modulator = new p5.Oscillator('sawtooth'); + * modulator.disconnect(); + * modulator.amp(1); + * modulator.freq(4); + * modulator.start(); + * + * // Modulator's default amplitude range is -1 to 1. + * // Multiply it by -200, so the range is -200 to 200 + * // then add 220 so the range is 20 to 420 + * carrier.freq( modulator.mult(-200).add(220) ); + * } + *

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

The first parameter is a name so that the phrase can be + * modified or deleted later.
