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.

var context = require('audio-context')
|
||
|
|
|

// Get array buffer from any object

ab = toArrayBuffer(new Buffer(100))

ab = toArrayBuffer(new Float32Array(12))
|

ab = toArrayBuffer(dataURIstr)

ab = toArrayBuffer(base64str)
|

ab = toArrayBuffer(ndarray)
|

ab = toArrayBuffer([[0, 1, 0], [1, 0, 1]])
