About the use of playing PCM arrays and WAVInterp16OneShotSourceFract32 modules

I have an array of audio stored in stm32, formatted as PCM. How do I play directly in Audio Weaver? Can the WAVInterp16OneShotSourceFract32 module achieve this function? Can you provide instructions for how to use this module? I tried testing this module, but can not find a pointer and fRatio to match the input signal.

Thank you!
