Мне нужно преобразовать ссылку типа https://soundcloud.com/ty-segall-official/saturday-pt-2-live?utm_source=clipboard&utm_medium=text&utm_campaign=social_sharing в embded типа: <iframe width=“100%” height=“300” scrolling=“no” frameborder=“no” allow=“autoplay” src=“https://w.soundcloud.com/player/?url=https%3A//api.soundcloud.com/tracks/1431306373&color=%23ff5500&auto_play=false&hide_related=false&show_comments=true&show_user=true&show_reposts=false&show_teaser=true&visual=true”></iframe><div style=“font-size: 10px; color: #cccccc;line-break: anywhere;word-break: normal;overflow: hidden;white-space: nowrap;text-overflow: ellipsis; font-family: Interstate,Lucida Grande,Lucida Sans Unicode,Lucida Sans,Garuda,Verdana,Tahoma,sans-serif;font-weight: 100;”><a href=“https://soundcloud.com/ty-segall-official” title=“Ty Segall” target=“_blank” style=“color: #cccccc; text-decoration: none;”>Ty Segall</a> · <a href=“https://soundcloud.com/ty-segall-official/saturday-pt-2-live” title=“Saturday Pt. 2 (Live)” target=“_blank” style=“color: #cccccc; text-decoration: none;”>Saturday Pt. 2 (Live)</a></div>

чтобы пользователь мог просто вставить НОРМАЛЬНУЮ ссылку типа https://soundcloud.com/ty-segall-official/saturday-pt-2-live?utm_source=clipboard&utm_medium=text&utm_campaign=social_sharing и вставлялся плеер в profile.ejs

Учти, что API soundcloud больше не предоставляет. например, можно использовать player.js
