Chrome DevTools: Inspect Audio with the Web Audio Inspector

You can use the Web Audio Inspector to inspect the details of AudioContexts - part of the Web Audio API. The Audio Inspector within Chrome DevTools displays information such as:

• State (running)
• Sample rate (44100Hz)
• Callback Buffer Size (256 frames)
• Max Output Channels (2 ch)
• Current play time (10.2s)
• Callback Interval (5ms)
• Render Capacity (1.2%)

You can try the Web Audio Inspector on a page which uses the Web Audio API, such as webaudioapi.com. Select WebAudio from the DevTools drawer (Three dots > More Tools > WebAudio).
