to-array-buffer

Turn any binary data container into an ArrayBuffer in sync way. Detected containers:

• Buffer
• TypedArray
• ArrayBufferView
• ArrayBuffer
• data-uri string
• base64 string
• plain string
• Array
• Array of Arrays
• Number (creates new ArrayBuffer of the defined length in bytes)
• etc.

It also handles some custom data types, like ImageData, AudioBuffer etc., but in general it returns null for objects not looking like binary data containers. Note also that it does not handle Blob and File, since they require async API.

1var toArrayBuffer = require('to-array-buffer')
2var context = require('audio-context')

4// Get array buffer from any object
5ab = toArrayBuffer(new Buffer(100))
6ab = toArrayBuffer(new Float32Array(12))
7ab = toArrayBuffer(dataURIstr)
8ab = toArrayBuffer(base64str)
9ab = toArrayBuffer(ndarray)
10ab = toArrayBuffer([[0, 1, 0], [1, 0, 1]])
