.ADD- Ambisonics Decoder Description

dotadd for JavaScript

This repository contains the integration of the .add-format functionalities for a JavaScript environment. Following is described what the possibilities are and how to use them.

Guide

To setup the JavaScript library only a few lines of code are necessary. First we begin with the necessary imports:

const { ADD, Matrix, Filter } = require('./cjs/dotadd');

Second the ADD.-object has to be declared and at least on matrix loaded:

let add = new ADD();
let mat = new Matrix("sn3d", [[1, 0, 0, 0],[1, 0, 0, 0]]);
mat.setWeighting("maxre"); // optional value as example
add.addMatrix(mat);

If needed you can add components using:

add.addOutput(OutputChannel("Name", "Type", {"a": float, "e": float})
add.addFilter(Filter.makeLowpass("Name", 100) // choose a frequency

You can also use valid() to check for completeness of a component or add.repair() to create missing metadata and default components from the matrices. There are many other functions you can use so please try around what is possible.
