I also save audio from YT occasionally. I prefer to use this command however (to get the best quality audio):<p><pre><code>    youtube-dl -f bestaudio[ext=m4a] &lt;youtube ID&gt;
</code></pre>
PS: you can replace m4a with mp3 but that will induce trasnscoding and loss of quality. YT&#x27;s AAC tracks are usually the highest bitrate ones so it&#x27;s best to leave it as is.
