## Remarks

若要获取每次运行时当前要解码的子帧数量,请使用 [GetShapeXmaNumSubframesToDecode](/reference/audio/shapexmacontext/functions/getshapexmanumsubframestodecode)。

若要设置要跳过的子帧数量,请使用 [SetShapeXmaNumSubframesToSkip](/reference/audio/shapexmacontext/functions/setshapexmanumsubframestoskip)。

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。
