The put_Interleaving method sets the audio preroll time and the frequency of the interleaving.
HRESULT put_Interleaving( const REFERENCE_TIME *prtInterleave, const REFERENCE_TIME *prtPreroll );
[in] Pointer to the frequency of the streams in the file, in 100-nanosecond units.
[in] Pointer to the audio preroll, in 100-nanosecond units.
Returns an HRESULT value that depends on the implementation of the interface.
An audio preroll of 750 milliseconds is recommended when authoring a file for distribution.
The default value for prtInterleave is 1000 milliseconds; however, you can adjust this. The smaller the number, the larger the file.
