Getting Started with Web Audio API
A port of an example used in the Getting Started with Web Audio API article by Boris Smus, originally published on HTML5Rocks.
You can use the Web Audio API for processing and synthesizing audio in web applications. The API lets you use functionality found in modern game audio engines and mixing, processing, and filtering tasks found in modern desktop audio production applications.
The example lets you enable and disable a lowpass filter via a checkbox, as well as tweak the frequency and quality values with a slider.
