I took two videos today, hopefully you can hear the noise a bit better. The first video is light revving between 2000 and 3000 rpm:

The second video is more aggressive revving:

That is some intense knocking. The bearing must be entirely pounded out to be that noisy. I find it really strange nothing is in the oil. Did you simply pull the stick to check for material or did you drain the oil? If you only pulled the stick then you probably will not see anything. If you drained the oil and nothing came out then I’d say it’s not a bearing. Maybe an ejected rocker or something. If the oil was just over the bottom dot then you aren’t low enough to cause issues. The bottom dot marks the 1qt low mark. It’s not great to be almost a qt low but it’s not automatic spun bearing territory.
What year is your car?
Also, don’t do anymore revving of the engine or driving until you figure out what it is.
