Audio Levels

  • Most Broadcast Engineers in North America calibrate their audio gear to nominal reference level of 0 dB on a VU meter aligned to +4dBu or –20dBFS.
  • Broadcast audio should have a good signal to noise ratio, where the speech (or music) is a minimum of 16dB above the noise of the recording.
  • Peak signal levels must not exceed - 6 dBFS or the nominal level by more than +10dB.
