<br><br>The recipe linked below plays sounds composed of a fundamental and a few harmonics. It requires Pygame and NumPy. <br><br><a href="http://osdir.com/ml/culture.people.kragen.hacks/2007-11/msg00000.html">http://osdir.com/ml/culture.people.kragen.hacks/2007-11/msg00000.html</a><br>
<br>It is out of date, though. I had to change 'Numeric' to 'numpy' and 'Int16' to 'int16' to get it to work. Moreover NumPy doesn't seem to work with Python 2.6.<br><br><br>You can also use TkSnack (<a href="http://www.speech.kth.se/snack/">http://www.speech.kth.se/snack/</a>). Check the example named 'notescale' that comes with the module: it defines a function that receives a frequency as an input and plays a sound; there is also a graphical interface.<br>
