Paul C,<br><br>I seem to remeber getting into Jack programming using a Jack module for python... just looked it up from my backup of programming projects, &quot;pyjack&quot; is the name of the module, i was using version 0.1 at the time. It allows capture / playback of &quot;standard&quot; python arrays of floats.<br>
<br>Project is currently located at:<br><a href="http://sourceforge.net/projects/py-jack/files/py-jack/">http://sourceforge.net/projects/py-jack/files/py-jack/</a>  and is at version 0.5.2.<br><br>HTH, -Harry<br>
