Load Audio from persistentDataPath in runtime (Unity3d WebGL)

Question

I have online/offline project. I need to download wav/ogg/mp3 file from Application.persistentDataPath on WebGL platform.

I tried www/webrequest.

For example - WWW("file://" + Application.persistentDataPath + filePath);

But always get error: Failed to load: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https.

Could you help me?

P.S. From remote server works fine.

You can not load local files in a browser as it's a security risk. If you could then a webpage could read your hard drive and steal all your files.

If you're just testing you can run a local server.

If you want to let the user supply a file you can let them choose a file
