      Hi Bhavin,
       
      I did not try before, but you can search about Pulse with modulation method. Example:
      - We generate 8000 cycle per second (125us period).
      - In each cycle:
          Level 255 will be outputed as signal 1 in 125 us.
          Level 127 will be outputed as signal 1 in 62.5 us.
          Level 0 will be outputed as signal 1 in 0 us.
      - Output will be connected with a simple filter circuit (RC circuit) before reach the audio amplifier.
       
      Best regards,
       
      Vu Trung Hieu.
