Hello All,
I am also working on the same line to capture sound data of Voice
Conference
over the net( input from mic and output of speaker.)
Where by I want to capture as well as do the normal activity for sound. (
IE. for
speaker Capture and Play as well )
I have tried till now as follows.
1. Capturing sound with Windows Media Encoder V9. with having KMixer
selected. As without mixer I can capture only mic and not the speaker.
- This works fine for stand alone PC but when I tried to capture voice
conference then sound quality gets BED, Very BED.
2. Now am trying to develop filter driver to capture sound in-out. But
unable
to connect to Sound driver object only... am quite confused as to sample
of CTRL2CAP dose work for Keyboard but when I try to attach to sound it
dose not provide me access to sound driver object.
If any one can guide me the BEST way to do the above task. Can be in any
technology will also do.
As I am ready to make research on any technology for the task to capture
sound from IN-OUT.
Thanks to all in advance
Bipin Mistry.
