If I understood you correctly, you'd like to record the output of your
soundcard, right?

Although this ain't an ffmpeg-question (because that's about general
sound-recording settings on your OS), here are some quick infos about
how you could achieve this:

1) Depending on your soundcard, you might be able to record the output
signal internally
For example: SoundBlaster cards had this option called "What U Hear"
(See HowTo: [1]).
If not, then you'll have to wire the output (green jack) of your card to
the line-in (blue jack).

2) Set the line-in as input source.

3) Playback & record.

Good luck.
