Using the synchronization facilities of MSP.

var inputStream = ...;
var timeToStartRecordingInputStreamAt = 10.371; // in the inputStream's
var durationToRecord = 5.31;
var p = new ProcessedMediaStream();
p.addInput(inputStream, 0,
var recorder = p.record();

(One minor issue with the current MSP spec is that there's no way to create
a ProcessedMediaStream with no inputs but with autoFinish set to true,
which is needed here, but that's trivial to fix.)

“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]
