Downloading audio (.webm) only is very slow?

[StefH]

I'm using this code:

var youTube = YouTube.Default; // starting point for YouTube actions
var videos = await youTube.GetAllVideosAsync("https://www.youtube.com/watch?v=spVJOzF0EJ0");
var v = videos.ToList();

var audio = v.Where(vi => vi.AdaptiveKind == AdaptiveKind.Audio).OrderByDescending(vi => vi.AudioBitrate).First();

Console.WriteLine(DateTime.Now.ToString("O"));
var bytes = await audio.GetBytesAsync();
Console.WriteLine(DateTime.Now.ToString("O"));

await File.WriteAllBytesAsync("c:\\dev\\" + audio.FullName, bytes);

And downloading a 7 MB audio file takes ~ 50 seconds ?:

Hello @nycr0x, for now I use https://github.com/Tyrrrz/YoutubeExplode which is faster.

For my example project see: https://github.com/StefH/Blazor.YouTubeDownloader.
