Is switch.app part of the Wave Pad software? I have been using the free version for a long time now and it suits my purposes very well. A good pogram. I'm on iMac running Snow Leopard.
According to the official website, there is no information regarding the switch.app utility. It's possible to be a part of the WavePad Sound Editor, but you need to contact the developer on the page mentioned for more information regarding this issue.
