Only audio file as visible to screen readers?
I’d say best practice is the reverse of what you suggest. If I was creating it I'd go the other way on this. Keep the slide text visible to screen readers and hide only the decorative images. Deaf-blind users relying on Braille display can't access audio at all, and audio can't be skimmed or navigated the way text can. Autoplaying narration also talks over screen reader speech (WCAG 1.4.2), so make sure it can be paused. You mention your audio adds information beyond the slide text, that extra content needs a text form too, captions or a notes transcript (1.2.1).
