Wave Repair is not freeware; it is shareware. After the initial 30 day trial period, it must
be registered in order to continue using it. Registration costs 30 US dollars; for
payment methods see the registration page.
However, some of the facilities continue to work without time limit:
If you only want to use Wave Repair for hard disk recording and
track splitting, it can be considered "freeware".
There is no need to register it in this case. (You will, of course,
have to put up with the "unregistered copy" screen which appears
once each time the program starts up. So in a formal sense it isn't "freeware" -
some people describe this mode of operation as "nagware").
