BaseAudioContext.createScriptProcessor() - Web APIs
the createscriptprocessor() method of the baseaudiocontext interface creates a scriptprocessornode used for direct audio processing.

ScriptProcessorNode - Web APIs
the size of the input and output buffer are defined at the creation time, when the audiocontext.createscriptprocessor() method is called (both are defined by audiocontext.createscriptprocessor()'s buffersize parameter).

Migrating from webkitAudioContext - Web APIs
createjavascriptnode() has been renamed to createscriptprocessor.
... if your code uses either of these names, like in the example below : // old method names var gain = context.creategainnode(); var delay = context.createdelaynode(); var js = context.createjavascriptnode(1024); you can simply rename the methods to look like this: // new method names var gain = context.creategain(); var delay = context.createdelay(); var js = context.createscriptprocessor(1024); the semantics of these methods remain the same in the renamed versions.

AudioContext.createJavaScriptNode() - Web APIs
important: this method is obsolete, and has been renamed to audiocontext.createscriptprocessor().

BaseAudioContext - Web APIs
baseaudiocontext.createscriptprocessor() creates a scriptprocessornode, which can be used for direct audio processing via javascript.
