How do I register ?

Can I use BPM Wizard on a program digital sound output (like winamp) ?

I started the program but nothing is happening !

I am writing an application that needs BPM. Can you provide a DLL/source code/Active X control for this purpose ?

You cannot register. BPM Wizard is delivered as is, with no limitation but with advertisements.

It depends. Full duplex sound cards can do this ( They can record their sound output). You will see that in the Windows sound mixer in the recording settings, if you have a loopback device (it might not be called loopback though...).

Your sound mixer might not be configured properly. Go back to the documentation page 'Setting the Windows sound mixer'.

Sorry, but no.
