T8b949e"""

Support for playing AudioSegments. Pyaudio will be used if it's installed,

otherwise will fallback to ffplay. Pyaudio is a *much* nicer solution, but

is tricky to install. See my notes on installing pyaudio in a virtualenv (on

OSX 10.10): https://gist.github.com/jiaaro/9767512210a1d80a8a0d
