You can see an example on how to use multiprocessing.Pool at

This is ogg -> mp3 but the same idea.

Thanks for the replies. I have a Queue object in the main GUI thread,
this gets passed to all the worker threads and they add items to it.
This is all well and good, but what is a good way to get the GUI thread
to send items back to the worker threads?

Look inthe demo that comes with wxPython it is in tree process and
events -> threads .
There is a nice demo of PostEvent().
Another way would be to use Queues as others have mention .
You can create a new frame and have it call the queue for data.
