Hi,
I've written a simple C++ class which wraps CoreAudio to play sound
from a given device through the default output unit. The audio device
is a video and sound capture card. So, I want to use this class in
conjunction with a quicktime sequencegrabber in a TV application. The
sequencegrabber should display the video on screen and my wrapper
should play the corresponding sound.
This works well in preview mode, but if I want to record a video with
sound on disk, I have to stop my wrapper and I have to use the
sequencegrabber and it's soundchannel to capture the sound data.
The problem is, that the sound in the resulting quicktime file sounds
like a roboter voice. If I don't use my wrapper for preview before I
don't get this effect.
It would be nice if anybody can point me in the right direction.
-- Andreas
