[Àû¿ë´ë»ó: DOSBox-x]

Minimum DMA transfer left to increase attention across DSP blocks, in milliseconds.

Set to -1 for default.
There are some DOS games/demos that use single-cycle DSP playback in their music tracker and they micromanage the DMA transfer per block poorly in a way that causes popping and artifacts.

Setting this option to 0 for such DOS applications may reduce audible popping and artifacts.
