[Àû¿ë´ë»ó: DOSBox-x]

If set, Gravis Ultrasound audio output is rendered at a fixed sample rate specified by 'gusrate'.

This can provide better quality than real hardware,
if desired. Else, Gravis Ultrasound emulation will change the sample rate of it's output according to the number of active channels, just like real hardware.

Note: DOSBox-X defaults to 'false', while mainline DOSBox SVN is currently hardcoded to render as if this setting is 'true'.
