Record playback and line-in sounds

[SaherAlim]

Hi,

How can I record line-in and playback music simutaniously. Basically I
want to merge two sounds. One comming from mic and the other is the
played music from PC. i can access line-in (mic) from multiple
API's.(Directsound, wavein) but I am unable find a way to record
currently playing sounds. Is there a way to access data from sound
card?
Any help in this regard will be of great help.

Thanks,

Saher

Saher,

I am absolute a nitwit in sound. However did you have already the DirectX 9c
SDK.

I know at least that you can do enormous lot of things with sound with that
as long as it is WAV.

The VBNet sample in that is in my opinion unusable. However the DirectSounds
samples in C# are easy to translate. (You can remove those links to that C#
helperproject that in it than, that does nothing).

I hope this helps,

Thanks Cor,

Yes i do have DirectX 9c SDK, but i am unable find any function to get
data from currently playing buffer. Can somone point me to relitively
specific pointers.

Thanks and regards,

Saher,

Did you look at the sample in the SDK
AdjustSound?

Have you already had a look at

Managed docs
DirectX SDK
Introducing DirectX 9.0
DirectSound
Capturing Waveforms

?

You'll get best MDX specific information @

Thanks all,

For reference one can do this by using directshow but only with C++
