Reference > Wave

Wave(size) is a class that creates the wave objects that store sounds in synthesine. A wave is an array of 32 bit floating point numbers, along with some prebuilt functions to manipulate waves.

• size (optional) This sets the size of the array. Typically we leave this empty. If unspecified, the length of a wave is set to numSamples, which is 128 by default.

Wave is an extension of javascript’s built-in Float32Array, so it inherits all the Float32Array methods.

Usage

• new Wave() creates an empty wave.
• new Wave().fill(0.1) creates a wave filled with the value 0.1
• new Wave().map((e,i) => i/128) creates a wave with 128 equally spaced values from 0 to 1

Wave Manipulation Functions

• .add adds two waves together
• .sub subtracts one wave from another
• .mult multiples two waves or multiplies a wave with a number
• .div divides two waves or divides a wave with a number
• .modulate modulates one wave with another wave

You can find the code for Wave in the synthesine library.
