Sorry for the quality of these files, im still fine tuning my recording skills... :-)
If your on a windows/mac machine, the easiest way to listen to these files is by downloading QuickTime. You can also right-click the link, and select 'Save file as' to save it to your local disk. Then use the windows media player to view it.
If your on a unix machine, sox will probably be the easiest to use.
