Play audio in python

[francibal]

Ciao a tutti,
I need always help ... (do you hate me?)

I've see that with csound in python i can create an audio file (like example by Mr. Gogins using SoundFile, etc.), i can open, change, save, but then if I want to play this audio file into python, without using externals like audacity, how I can do it ? It's possible with csnd/CsoundAC modules, or I need use somethings like winsound module of python ?

Sorry, but i will be always a beginner ...

Thanks and ciao,

fran.

There are several ways to play audio directly from Python.

(1) You can indeed do it using the Csound API, using a Csound
instrument that reads in the soundfile and simply sends it to the
audio output, with realtime command-line options. I have done this, it
is easy, and it works fine.

(2) In addition to Pyaudio, there are several Python extensions for
sending audio to the sound card. You can see most of them at the
Python Package Index on the Python home page or at
http://pypi.python.org/pypi?:action=browse&show=all&c=338&c=352. In
addition, there is the Snack toolkit for extending Tk with audio for
Tcl and Python at http://www.speech.kth.se/snack.

(3) You can use Python's ctypes module to access your operating system
calls for audio output -- open an audio port, set it up, and send data
to it. I haven't tried this, but I have used ctypes to query for audio
port capabilities. That worked fine, and I think output would work
fine also.

Hope this helps,
Mike
