## Remarks

若要获取输出缓冲区的大小,请使用 [GetShapeXmaOutputBufferSize](/reference/audio/shapexmacontext/functions/getshapexmaoutputbuffersize)。

若要设置输入缓冲区的大小,请使用 [SetShapeXmaInputBuffer0Size](/reference/audio/shapexmacontext/functions/setshapexmainputbuffer0size) 和 [SetShapeXmaInputBuffer1Size](/reference/audio/shapexmacontext/functions/setshapexmainputbuffer1size)。

有关详细信息,请参阅 [SHAPE 概述](/build/console-features/audio/overviews/shape-overview)的 [XMA](/build/console-features/audio/overviews/shape-overview#ID4EYD) 部分。
