)  
```

*numChannels*   \
Type: UINT32

## Remarks

This function sets the actual number of channels in the context. (In the [SHAPE\_XMA\_CONTEXT](https://docs.xbox.com/reference/audio/shapexmacontext/structs/shape_xma_context.md) object, the `numChannels` member contains the values 0 \[mono] or 1 \[stereo].)

To get the current number of channels, use [GetShapeXmaNumChannels](https://docs.xbox.com/reference/audio/shapexmacontext/functions/getshapexmanumchannels.md).
