I don't see anything on this tracker representing unprefixing the AudioContext constructor. Any specific reasons why it can't be unprefixed, given it was implemented since Safari 6?

It looks like WebKit is the only engine where AudioContext is still prefixed: https://developer.mozilla.org/en-US/docs/Web/API/AudioContext#Browser_compatibility (As webkitAudioContext)
Tests in WPT checking that the prefixed variant doesn't exist: https://wpt.fyi/results/webaudio/historical.html?label=master&label=experimental&product=chrome&product=firefox&product=safari&aligned
Hmm, it also looks like a lot of tests are failing or not run because of this. Example: https://wpt.fyi/results/webaudio/the-audio-api/the-audiobuffer-interface/audiobuffer.html?run_id=595470001&run_id=613910001&run_id=608350001
Duping to where it got enabled. *** This bug has been marked as a duplicate of bug 216885 ***
