+                By default, WASAPI will operate in shared mode. Set it to 1 (TRUE) to use WASAPI in exclusive mode. In this mode, you'll benefit from direct soundcard access via kernel streaming, which has an extremely low latency. However, you must pay close attention to other settings, such as synth.sample-rate and audio.sample-format as your soundcard may not accept any possible sample configuration.
