Some videos' audio is white noise when opened in video editor Vegas. #294

The videos play fine in video players, but in my video editor the audio is loud white noise. I looked at 4 videos' properties and the 3 which were noise had audio sample rates of 48,000 kHz, while the one that worked had 44,100 kHz. Perhaps that's just coincidence - perhaps that's not the "reason" for the unwanted behaviour. I was downloading 360p mp4s.

I then downloaded one of the failed videos using 4K downloader and it downloaded at 44,100 kHz and it worked.

Would it help if YouTube Playlist Downloader had an option to set to audio sample rate to 44,100 or "not 48,000"? Want someone to test that if you add that option to a test version?

@shaked6540, can there be a way to force videos to download with audio sample rate 44100 kHz instead of 48000 kHz?
I can confirm that videos downloaded with 48000 kHz audio sample rates play white noise instead of the proper audio in software like the video editor Magix Vegas, even though the same file plays properly in VLC, and even though Vegas plays other 48000 kHz videos (not downloaded using YTPD) no problem.

I don't think its possible, I'm not sure if youtube gives this information before downloading. Its a problem with the video editor that you're using, most likely it doesn't support that specific sample rate. I'm not an expert on audio codec and what the sample rate means, but there are probably ways to convert it from 48000 kHz to 44100 kHz.

If VLC is able to play it, the file is ok. VLC is using the most up to date libraries, so its able to handle everything.

And as I've said, I'm not an expert when it comes to technical things like that, I'm just downloading whatever youtube is giving
