I had already tried as the described in the link you mentioned but the
audio capture was not satisfactory. The quality of sound was low. So,
i thought of going for a filter driver. I understand using
WaveIn/Wasapi API for Vista and Win 7. But my requirement is for Win
XP as well.

For Win XP i need a filter driver to record the PC audio. Is this
correct? If so, at what level in audio stack i need this filter driver
to be present? Any info or samples would be much helpful.
