"""Class for internal object to make an audio recording using pyo.
Never needed by end-users; only used internally in __init__:
self.recorder = _Recorder(None) # instantiate, global
Then in record(), do:
self.recorder.run(filename, sec)
This sets recording parameters, starts recording.
To stop a recording that is in progress, do
self.stop()
This class never handles blocking; AudioCapture has to do that.
Motivation: Doing pyo Record from within a function worked most of the time,
but failed catastrophically ~1% of time with a bus error. Seemed to be due to
a namespace scoping issue, which using globals seemed to fix; see pyo mailing
list, 7 April 2012. This draws heavily on Olivier Belanger's solution.
