Can someone help me to use Google Gemini API1.5Pro model with Video/audio Processing?

I’ve already searched almost in all search engines, but can’t find any resource to learn.
My requirement is to upload an audio file and ask the AI to summarize it.

I’m using Node.js with Google AI Studio(@google/generative-ai)
any suggestion will be highly valued!

I’ve tried the following:-

• I’ve installed the google generative package and explore with it
  the Gemini AI API1.5Pro is working perfectly with text-only results and text-and/or-image results, but I couldn’t find any way to explore with audio files and video files.
