Hi Hans,


Your best bet is probably the pygame module:

    http://pygame.org/


In fact:

    http://pygame.org/docs/ref/pygame_sndarray.html

uses Numeric Python arrays to generate sounds.

    http://archives.seul.org/pygame/users/Nov-2002/msg00120.html

shows sample code to play a sound out of a Numeric Python array.



However, PyGame has not have adopted 'numarray' yet: it looks like they're
still using the older Numeric Python 'numpy' library.

The switch to 'numarray' appears to be a TODO for the PyGame folks:

Until then, it might be easiest to use Numeric Python's arrays with
PyGame.


Good luck to you!
