Hi, I'm using your Library to extract mp3 from Youtube URL. It's so nice and useful to me.

But, I have a question that 'How to extract mp3 URL or file from 'Youtube(url:)' object'. There is no mp3 type in Audio and I can't find out any mp3 type in AudioCodec obeject.

This is the sample I used.

You should use .filterAudioOnly() if you want audio file. Look at https://github.com/alexeichhorn/YouTubeKit?tab=readme-ov-file#example-2 for a full example.

Oh! I used that method for extracting mp3, But it was very long time to get. ex) It was 4min Youtube Video, but I need to wait for 2min to get audio from 'url' one of filterAudioOnly() properties 🥲🥲

I assume your download is slow. This is YouTube throttling you. Maybe look into #17 where I describe some ways to circumvent that.
