[Cs-dev] [OT] Python question

I have a python program that was written for windows, but as far as i can tell the only windows component is the use of winsound and one line winsound.PlaySound(filename, winsound.SND_FILENAME|winsound.SND_ASYNC) It was suggested to me that on Linux one uses ossaudiodev but I cannot find an equivalent call -- remember that I do not talk python and it all looks like Egyptian to me. Any fixes, suggestions, pointers to readable documentation or... ? ==John ffitch ------------------------------------------------------------------------------ _______________________________________________ Csound-devel mailing list Csound-devel@lists.sourceforge.net |

I found this with the help of google, though oss hardly seems a good api to be using:
file='tada.wav'
if platform.startswith('win'):
from winsound import PlaySound, SND_FILENAME, SND_ASYNC
PlaySound(file, SND_FILENAME|SND_ASYNC)
elif platform.find('linux')>-1:
from wave import open as waveOpen
from ossaudiodev import open as ossOpen
s = waveOpen('tada.wav','rb')
(nc,sw,fr,nf,comptype, compname) = s.getparams( )
dsp = ossOpen('/dev/dsp','w')
try:
from ossaudiodev import AFMT_S16_NE
except ImportError:
if byteorder == "little":
AFMT_S16_NE = ossaudiodev.AFMT_S16_LE
else:
AFMT_S16_NE = ossaudiodev.AFMT_S16_BE
dsp.setparameters(AFMT_S16_NE, nc, fr)
data = s.readframes(nf)
s.close()
dsp.write(data)
dsp.close()
there is also a portaudio binding for python at http://people.csail.mit.edu/hubert/pyaudio/

| Hi, I'm actually writing a Python module for dsp called pyo. It doesn't yet compile on Windows but on OS X and linux it works well. All info are on googlecode: http://code.google.com/p/pyo/ http://code.google.com/p/pyo/wiki/Installation http://www.iact.umontreal.ca/pyo/manual/ It's in alpha stage (first release at the end of the summer) but functional and very simple to use: from pyo import * s = Server().boot() s.start() a = SfPlayer(path=filename, speed=1, loop=True).out() It can be a good option! There is examples in the sources... Olivier
