Hi everyone, my diploma project is to develop an echo canceler for controlling application with speech. For this purpose, I need to know what a sound card is currently playing. I was trying to find out how to read the DMA buffer which contains mixed samples prepared to be passed to the sound card. Is there any API call to do this? The second thing - What is the best way to allow applications to access the echo-cancelled microphone input?
