FM Transmitter

Good evening Mr Hamster
The project is very interesting. I am a student and if u Could you help me?. I want to send audio. You said, audio with 16-bit resolution high quality mono. 1221381325 + / - 1.000.000

but I don´t understood very well that I add audio input in the process.,and what signal I  use.
 

This would be:

if beep_counter(19) = '1' then
               phase_accumulator <= phase_accumulator + 1222381325;
            else
               phase_accumulator <= phase_accumulator + 1220381325;
            end if;
         else
            phase_accumulator <= phase_accumulator + 1221381325; -- +/-1000000
         end if;
