Web Audio seems as it's name suggests focused solely on audio and
delivers a rich framework for realtime audio processing and
synthesizing.

MediaStream Processing seems like a "simpler" solution, yet it delivers
a more integrated stream solution across both audio and video.

I could imagine treating Web Audio as a layer on top of the MediaStream
Processing API linked together through the <audio> HTMLMediaElement.  
https://dvcs.w3.org/hg/audio/raw-file/tip/webaudio/specification.html#AudioElementIntegration-section
http://hg.mozilla.org/users/rocallahan_mozilla.com/specs/raw-file/tip/StreamProcessing/StreamProcessing.html#media-elements 

In fact the MediaStream Processing API proposal even suggests this type
of layering:

        The API presented here does not include a library of "native"
        effects; those should be added as a clean extension to
        StreamProcessor, perhaps as a "level 2" spec.
        
So from a web dev's point of view it would be nice to have the freedom
to stack these two solutions like this.

But if only one were to be adopted then the MediaStream Processing API
would open up a much wider range of opportunities/innovations and seems
like it could work more seamlessly with webrtc.
