Dsound Audio
vinaykabadi
I use Dsound for capture playback. I use 2 threads to start the
capture and playback at the same time and there is no delay in
initiating the threads but still when I compare the played file and
the captured file I find a initial delay of 60ms in the captured
file.
(I use loop back (connect the capture and playback by a wire) that
there is no delay in the air)
Do the Dsound playback take some time to pass the data from buffer to
the device ???
I think this is the reason.. When I read the audio data from a
data_file and write it into a file which will be played file, on the
other hand whatever is coming from the play device is captured and
written into a file, if the delay lies in Dsound playback to send the
datd from buffer to device then it obviously will show the delay.
If this is the case then I would like to know exactly how this delay
can be calculated or come to known..
