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
