youtube_dl get audio link with Python

Question

I'm trying to retrieve the link for the audio only file on youtube using youtube_dl. I wonder if it's possible to do so. I'm using youtube_dl as in python code not with terminal.

Many thanks

If you want to download the audio only, you can do this,

ydl_opts = {
    'format': 'bestaudio/best',
    'postprocessors': [{
        'key': 'FFmpegExtractAudio',
        'preferredcodec': 'mp3',
        'preferredquality': '192',
    }],
    'outtmpl': '%(title)s.%(etx)s',
    'quiet': False
}

with youtube_dl.YoutubeDL(ydl_opts) as ydl:
    ydl.download([url])  # Download into the current working directory

This is a snippet of code I've taken out of a project I worked on. You can see the full source here:https://github.com/francium/audiosave/blob/master/audiosave.py
