Solutions:

  • Automatically calculate possible increase in volume after each task completion. If task is restarted, increase limiter volume in stage 0. This requires processing two times.
  • Create new task type. Take mp3 and maximize it. This is more difficult and will encode mp3 file two times.
  • After rendering of stage 0 is finished, start reaper and recompress mp3 with added compression. This will encode mp3 file two times. For testing purposes do this 100 times in a row

How to calculate volume increase before limiter:

  • Simplest method is get highest peak and calculate its headroom. Doing this will ensure that peak will get to the top. This method is also good to start with - so that algorithm is calibrated correctly.
  • Calculate RMS. If RMS is below -10 dB, increase signal, but to avoid overshooting more than 5 dB
