Hi @e.makarevich09,
Adalify should help here! ( Announcing Adalify: String functions, Twilio SMS, Add to Calendar , Adalify Customizable File Uploader - large uploads, crop photos, limit size, file types, stream video )
You can access the URL! Check this video : Musics.mp4 on Vimeo
In internal if you create a file property and upload the audios you can access audio file URL from magic text! In internal you can create a text property and add the audio file URL’s there and add that on the audio player component too! In external also same!
Thank you
