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.
