Processing streams of data. Read more in the docs

• clamp: Restrict a number to a given range
• clampIndex: Restrict a number to be within the size of an array
• flip: Invert a relative number
• interpolate: Mix between two numbers by an amount
• interpolateAngle: Mix between two angles by an amount
• scale: Scale a value from an input range to an output range
• wrap: Wraps a value to be within a range
• wrapInteger: Wraps an integer to be within a range
• Bipolar: Module for working with bipolar values

Averaging

• movingAverage: Calculates an average-over-time (movingAverageLight is a coarser, less memory-intensive version)

Normalise sub-module

• Normalise.stream: Normalises a stream of values
• Normalise.array: Normalises an array of values

Trackers

Trackers are useful for tracking a series of data over time.

• numberTracker: Tracks min, max and average of a stream of numbers

• intervalTracker: Tracks min, max and average time interval between events

• pointTracker: Tracks the spatial change of x,y coordinates. Useful for tracking a mouse cursor, for example.

• pointsTracker: Tracks changes in multiple x,y coordinates. Useful for tracking each finger touch on a screen, for example.

• frequencyMutable: Count occurences of a value

• Pool.Pool: Manage a shared set of resources

Example: Importing

// If library is stored two directories up under `ixfx/`
import {movingAverage} from '../../ixfx/dist/data.js';
// Import from web
import {movingAverage} from 'https://unpkg.com/ixfx/dist/data.js'
