Need help to extend a youtube video while keeping the same sound quality.

[piff]

Hello, not sure if this is the correct forum for this request. Got here from google AI reply when I asked about video help forums.

I tried to do this myself some year ago, by simply recording the video and putting it on a loop. But the sound quality was awful I do not recall what sound service I used.

I can´t simly loop the video since its a sleep video with wakeup bells at the end. (Its a youtube video).

It is basically the one sleep video I found that works great for me but it is too short. I need a 8 hour version and I do not know how to keep same sound quality while doing so. With the last 1min 25 seconds at the very end of the 8 hours. Just like in this 1h 30 min version. If anyone can help/suggest what to use so I can figure it out myself it would be appreciated.

This is the video: https://www.youtube.com/watch?v=AVmi67PbGVs

Audio only? Here you go https://gofile.io/d/CSmnkg
I added 17 minutes of sleep for you)) I know what it means to “not sleep”

P.S. Regarding “+17 minutes” — I'm not a sleep expert, but when opened the audio spectrogram, I saw the so-called three phases (as far as I could tell)
1 - falling asleep
2 - sleep
3 - waking up
So, in order not to mess up the order, I only cloned phase 2, leaving phases 1 and 3 untouched. That's why it turned out to be a little over 8 hours. But if you need to fix it, send me a PM.
