You can see that it uses three nodes: an OscillatorNode as the source, a GainNode to control the volume, and an GainNode as the destination. Here’s the graph for the Violent Theremin demo: The Web Audio Editor will now display the graph for the loaded audio context. The Violent Theremin, which changes the pitch and volume of a sine wave as you move the mouse pointer The Voice-change-O-Matic, which can apply various effects to the microphone input and also provides a visualisation of the result Click the tab and load a page that constructs an audio context. Now there should be an extra tab in the Toolbox toolbar labeled “Web Audio”. To enable it, open the Developer Tool Settings and check “Web Audio”.

If you have feedback or suggestions for new features, dev-developer-tools or Twitter are great places to register them. ![]() If you find bugs, we’d love it if you filed them in Bugzilla. Some non- AudioParam properties, like an OscillatorNode’s type property, are displayed, and you can edit these as well. You can then examine and edit the AudioParam properties for each node in the graph. This gives you a high-level view of its operation, and enables you to ensure that all the nodes are connected in the way you expect. The Web Audio Editor examines an audio context constructed in the page and provides a visualization of its graph. The developer connects the nodes in a graph, and the complete graph defines the behavior of the audio stream. For example, the GainNode has a single gain property, while the OscillatorNode has frequency and detune properties. Nodes representing the destination of the audio stream, such as the speakersĮach node has zero or more AudioParam properties that configure its operation. Nodes performing transformations such as delay and gain Nodes providing the audio source, such as an oscillator or a data buffer source With the Web Audio API, developers create an audio context Within that context they then construct a number of audio nodes, including: Notice: This tool has been deprecated and will soon be removed from Firefox.
