an AudioBuffer, the audio can then be played by being passed
an web.audio.AudioBufferSourceNode

The AudioBuffer interface represents a short audio asset residing memory, created from an audio file using the `AudioContext.decodeAudioData()` or from raw data using `AudioContext.createBuffer()`. Once put an AudioBuffer, the audio can then be played by being passed an `web.audio.AudioBufferSourceNode`.
(constructor & args)
Constructor.
The AudioBuffer constructor of the Web Audio API creates a new web.audio.AudioBuffer
object.
Inherits parameters from the web.audio.AudioNodeOptions
dictionary.
options Options are as follows:
length: The size of the audio buffer in sample-frames. To determine the length to use for a specific number of seconds of audio, use numSeconds * (sampleRate * numberOfChannels). numberOfChannels: The number of channels for the buffer. The default is 1, and all user agents are required to support at least 32 channels. sampleRate: The sample rate in Hz for the buffer. The default is the sample rate of the context used in constructing this object. User agents are required to support sample rates from 8,000 Hz to 96,000 Hz (but are allowed to go farther outside this range).
Deprecated parameters
context
A reference to an web.audio.AudioContext
. This parameter was removed from the spec.
