Description
You can adjust the driver's input and output audio buffer size.
Decrease the buffer size to decrease latency. Increase the buffer size if audio drops out.
If audio drops out or if noise is heard even if you have adjusted the buffer size setting
in the software and adjusted the "Audio Buffer Size" as explained above, increase the
recording margin setting.
Adjust this setting if the recorded audio data is not in time.
If the audio software is running, the new setting will not be applied immediately when
[Apply] is clicked. Quit all audio software; the new setting will be applied the next time
you start the software.
