Audio is loading too slow using script in OptimizedPress. Please help

Hi there,

I've built a website with OptimizedPress:
https://aanchorbiz.com/aiincomebreakthrough/

And I've built a script to be included in its header script section. What the script does is that upon page, it will scroll to one of the images, and play its corresponding narration audio. After that it will scroll to the next image and play its audio, and so on.

It takes a long time to load the page and play the first audio. Is there any way to make the audio load faster – like within the first few seconds upon page load?
