Hey guys, I''m not sure where to ask this, as it''s not a DirectX question, but it''s not about the creative side of audio either... I''m interested in capturing the total system sound output under Windows. Say I wanted to write a sound visualiser that worked with any MP3 player, and also reacted to the "you''ve got mail" sound, and error noises, and whatever other noises the PC happens to make... Obviously, I could do this by wiring the sound output jack to the mic input. Or by choosing "What U Hear" as my sampling input source. But I''d like to do it totally in software, and more neatly than that. I can''t see anything in the DirectSound docs for this, and I don''t know much about Win32. Does anyone have any ideas? Ideally what I''d like, is to be able to tell Windows, "here''s a circular buffer, please copy the final mixed system sound output into it, continuously". Is this possible? Thanks in advance for any suggestions or references!
