Inherits parameters from the AudioNodeOptions dictionary .

选项

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 : 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).

context: A reference to an AudioContext . This parameter was removed from the spec.

NotSupportedError: One or more of the options are negative or otherwise has an invalid value (such as numberOfChannels being higher than supported, or a sampleRate outside the nominal range).
