Hi Abilash,

There are multiple ways by which you can accomplish this.

If your hardware supports this, it might be as simple as recording from the
"What U Hear" (or some similar name) input source; some sound cards enable
the output of the sound card to be used as a recording source.

An alternative might be to attach a cable from your soundcard's output jack
right into it's input (line in) jack. Depending on your contraints and
needs this might suffice. I think that audio quality might not be as good
with this solution as it would be with other solutions though, but maybe it
won't be noticeable enough in your situation.

A third option might be to use a specialized audio driver that identifies
itself as a soundcard to the system. Then use this device as your preferred
sound output device, and the device can then pass you the audio data that
flows through it. But this requires you to install extra drivers, and if
you have to build it yourself that won't be an easy task. On the other
hand, there are pre-build application that work on this principle that you
might use ("Virtual Audio Cable" comes to mind, although I have never used
it, so I can't comment on the usefullness).

There might be more options than these, maybe someone else can add to this
list?

Kind regards,
Carl Colijn
