I would like to filter audio from microphone and out to the speaker. ( in real time) Means I'm trying to do thread in and out. P.S. Using Turbo C not Visual to keep a performance.

These groups are for Windows programming using C++Builder, not DOS programming. We can't help you.

They are no longer used by well-behaved applications under Win32, and in fact they are locked off from applications under WinNT/2K/XP. If you're planning to use your program on any WinNT-derived platform then you should find a 'nicer' way to access the sound card - either through the Win32 multimedia APIs or DirectSound. -- Corey Murtagh The Electric Monk "Quidquid latine dictum sit, altum viditur!"
