Import Custom Sounds?

So i know i can upload sounds into the game file to be used, but for my project I would like to enable to user to add sounds from their device; I've attempted using the file chooser to set a string variable of FileChooser.FileURLAt(0), and using the audio Play by name feature, but it seems it will only load things in your audio or music folders. would there be a way to allow a user to import sounds to be set to different sprites? the end project is a basic MPC, sixteen sprites, all linked to different sounds when you touch them. i can do it no problem with stock sounds, but it would be awesome if users could load their own samples onto the buttons.

The only way it seems possible is via a plugin or recording sounds via users microphone, which could prove interesting for a beatboxing mpc, so i guess ill try to go that route for now,but if anyone has ideas or suggestions itd be much appreciated.
