audio-context

audio-context

Creates a WebAudio context singleton with the given options. Returns null if not supported.

Example

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

You can also create an OfflineAudioContext in case you would like to process (faster) without any rendering.

var offlineContext = require('audio-context')({offline: true})

Usage

ctx = createContext(options|sampleRate)

Returns a singleton audio context for the given sampleRate.

The options:

• sampleRate - if specified, will set the context sampleRate.
• latencyHint - if specified, will control latency. One of 'balanced', 'playback', 'interaction' (default) or number.
• offline - if specified, will create OfflineAudioContext.
• length - if specified, will set number of frames for offline context.
• channels - if specified, will set number of channels for offline context.
• {...contextAttributes} any other options for the context.

Handles vendor prefixing for audio contexts. Returns null if we are not in a browser, or if the context is not available, or if there was an error creating the context.
