fix sending voice torpedo!

I have 2 files that are linked through a post. the problem is in the audio file. I need to send a public url to the api, ex: https://teste.com/audio/teste.mp3 but inside the audio folder there are other Mp3 files, I'm using a select. to choose the audio and sending eels by &audioUrl but I'm having problems! the api is reading the path name ex: /audio/teste.mp3 and not the url being sent!
