Is at fast

I'm sorry but that doesn't actually make any sense in English. Can you try to rephrase?

Blazing fast! Looked like a blur as it passed.

When you open your Podcast, you'll see in the bottom left corner something that says 1X. In your case, it'll say 1 1/2x or 2x, etc. Press this icon until you get back to 1X. Hope this helps!!
