## Remarks

To get the size of the output buffer, use [GetShapeXmaOutputBufferSize](/reference/audio/shapexmacontext/functions/getshapexmaoutputbuffersize).

To set the sizes of the input buffers, use [SetShapeXmaInputBuffer0Size](/reference/audio/shapexmacontext/functions/setshapexmainputbuffer0size) and [SetShapeXmaInputBuffer1Size](/reference/audio/shapexmacontext/functions/setshapexmainputbuffer1size).
