CPU benchmark utility hangs

[shariq-audiofocus]

When running the CPU benchmark utility (https://cdn.rawgit.com/resonance-audio/resonance-audio-web-sdk/master/examples/benchmark.html) it hangs.

Steps to Reproduce:

1. Open https://cdn.rawgit.com/resonance-audio/resonance-audio-web-sdk/master/examples/benchmark.html
2. Click Begin
3. Says 'Please Wait' for hours.
4. Happens in Chrome on OSX but I believe it's platform agnostic.

Underlying issue:
Looking in the Browser Console (F12) I see the following error:
benchmark.js:119 Uncaught TypeError: audioContext.createMediaElementSource is not a function at startBenchmark (benchmark.js:119)

which points to this code:

let audioContext = new OfflineAudioContext(numberOutputChannels, durationSeconds * sampleRate, sampleRate); let audioElementSource = audioContext.createMediaElementSource(audioElement);

It seems OfflineAudioContext no longer has the createMediaElementSource function (see WebAudio/web-audio-api#308 and https://developer.mozilla.org/en-US/docs/Web/API/BaseAudioContext). Looks like OfflineAudioContext now inherits from BaseAudioContext which does not have the necessary function.

This would be great to be fixed, as performance comparisons between the systems don't seem to exist anywhere else on the web.

Do you know if this could then be replaced with createBufferSource()?
