Save "blob" file

Hi,

I'm using this library: https://logbon72.github.io/angular-recorder

It creates a MP3 file (or wav) when you record which you can download.

I'd like to upload instead of download, so the file url blob is something like this:

blob:http://myapp.com/random-characterc76d2edd-6274-4138something.

What I want is to pass that "url" to the server and generate the MP3 FILE, and then save that path in database.

How can I achieve this task?

Thx.
