Low latency audio capture and output
I need to capture microphone audio, mix a reverb signal, plus the audio from a playing video, and output the mixed signal in real time for a karaoke application.
I've done this fine in the past using DirectShow on WinXP, but Windows 7 and later no longer has the ability to feed the live mic input to the output via hardware. Any capturing I do with DirectShow or WaveIn has an unacceptable delay, no matter how low I set the buffers. There is also no way to control the render buffers, as far as I can find, and I think this is where most of the delay comes from. So it looks like I'll need to use Kernel streaming or ASIO. I have no idea how, or even if I can extract the audio from a playing video file to mix with the captured signal. Is this something AudioLab could be used for? If so, is there any documentation that can help me get started? |
