Synchronized Simultaneous Playback and Recording

[abhayap]

Is it possible to get an option to get a synchronized simultaneous playback and record feature? I am recording impulse responses so this necessary.

I think this should be possible. Maybe first, we should add a unsafe_read_and_write! and read_and_write function to SampledSignals, and then write an unsafe_read_and_write! method here?

This turns out to be quite difficult to achieve in Julia through PortAudio. See my comment here: #37 (comment)
