### Parameters

*context*   \_In\_\
Type: [SHAPE\_XMA\_CONTEXT](/reference/audio/shapexmacontext/structs/shape_xma_context)\*

## Remarks

For guidance on XMA context loops, see [Guidelines for using SRC for PCM and XMA data](/build/console-features/audio/overviews/acp-overview#ID4EUPAC) in [ACP overview](/build/console-features/audio/overviews/acp-overview).

To set the start offset, use [SetShapeXmaLoopStartOffset](/reference/audio/shapexmacontext/functions/setshapexmaloopstartoffset).

For more information, see the [XMA](/build/console-features/audio/overviews/shape-overview#ID4EYD) section of [Overview of SHAPE](/build/console-features/audio/overviews/shape-overview).
