AudioContext Suspender — h43z

Many websites seem to be opening AudioContexts (through the Web Audio API https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API) without ever suspending them, even if they don't play any sound.

This leads to high CPU utilization and therefore increased energy consumption of your devices. Which can also lead to bluetooth audio problems.

This extension fixes that problem. It automatically suspends newly created AudioContexts after 2 seconds.

The extension resumes an already auto suspended AudioContext for another 2 seconds if it detects that the webpage wants to play another sound.

If a websites needs to play sounds continuously or longer than 2 seconds with the Web Audio API you can disable the extension for the website with a localstorage entry with the key disableAudioContextSuspender and some truthy value.
