Re: Audio-ISSUE-4 (quinnirill): Setting sample rates for individual JavaScriptProcessingNodes [Web Audio API]

MediaStreams Processing allows each stream to have its own sample rate and
automatically resamples inputs to a ProcessedMediaStream as necessary. The
sample rate for a ProcessedMediaStream can be set explicitly, otherwise is
explicitly set to the sample rate of the first audio data arriving on an
input stream.

I felt it was important because I wanted authors to be able to select some
media sources and hook up some effects to them without knowing in advance
what their sample rates are and without having to explicitly detect and set
sample rates --- while still not doing unnecessary resampling in the common
case that the inputs all have the same sample rate.

But I tell you, love your enemies and pray for those who persecute you,
that you may be children of your Father in heaven. ... If you love those
who love you, what reward will you get? Are not even the tax collectors
doing that? And if you greet only your own people, what are you doing more
than others?" [Matthew 5:43-47]
