This Space demonstrates the music structure analyzer predicts:
<ul
style="padding-left: 1rem;"
>
<li>BPM</li>
<li>Beats</li>
<li>Downbeats</li>
<li>Functional segment boundaries</li>
<li>Functional segment labels (e.g. intro, verse, chorus, bridge, outro)</li>
</ul>
</p>
<p>
It takes about 4:30 to analyze a 3-minute song.
If you are in a hurry, you can <strong><u>try the examples at the bottom</u></strong>.
