Trying to judge the source of any mechanical noise using that method is unreliable. I offered you the benefit of my personal experience since my engine sounded a bit like yours (in the second recording) until I renewed the ancillary belt tensioner plus the timing belt pulleys. I also similarly diagnosed a friend's KV6 earlier this year. He was sceptical too until his garage confirmed it.

Whilst I agree that nothing should be ruled out, I'd suggest a hand to feel exhaust gas pressure immediately after a cold start. However, I'm fairly confident that the 'check engine' light would illuminate under those circumstances and that hasn't been reported.
