Non-diegetic sound

We have been working on the non-diegetic sound for our film opening. We planned out that tension would build up until our main character collapses here after the music fades out. 

Above you can see the program we used to create most of the non-diegetic sound. 

Also we recorded a female and male talking in a reporters voice to lay over the start of the opening. We got some copyright free sound for American voices, this would show how far the disease has spread.
