I have a tool, where I must inform the exact link of the mp3 file contained in Soundcloud. In this case, it would not be the audio link itself but rather where the file is hosted. I am currently using link for this type of process.
If I get embedded from a file, it looks like this:
<iframe width="100%" height="300" scrolling="no" frameborder="no" allow="autoplay" src="https://w.soundcloud.com/player/?url=https%3A//api.soundcloud.com/tracks/328259811&color=%23ff5500&auto_play=false&hide_related=false&show_comments=true&show_user=true&show_reposts=false&show_teaser=true&visual=true"></iframe>
I tried to use what is after api.soundcloud ... and it still did not work.
