Doing it at the MediaStream level would easily handle dynamic adding and
removing of audio tracks. That might not be easy to do with Web Audio; it's
hard to tell because MediaStream/Web Audio interaction is very
underspecified at the moment.

“You have heard that it was said, ‘Love your neighbor and hate your enemy.’
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]
