Original issue's description:
> Fix test CastStreamingApiTestWithPixelOutput.EndToEnd.
> Update end_to_end_sender.js to use standard WebAudio API.
> Modify unit test to use a larger window size (previous window size was
> too small, which negatively impacted the median color computation
> routine.)
> 
> BUG=349599
