Default Knocking???

(See video) It seems to run well and it gets a tad bit worse with more rpm but nothing like these other knocking ls1’s that are super loud….but it still sounds like rod knock

It is very hard to determine if you have a rod knock based on a Audio file, For most here we would need to be standing at the open hood to give a useful opinion.

Very hard to discern with that generous 4 second clip.

But since we are playing name-that-tune......I'll take accessory noise for the win. Remove the belt, and run the engine to see if the noise goes away.
