Measuring Short-Term Loudness during Playback

You can record and display the short-term loudness during playback as a curve on the loudness track.

Procedure

  1. Select Project > Add Track > Loudness.

    A loudness track is added, and the EBU 128 reference loudness level of -23 LUFS (0 LU) is displayed as a horizontal line in the event display.

  2. In the track list for the loudness track, activate Activate Loudness Calculation.

    By default, loudness calculation is deactivated for performance reasons.

  3. Activate Enable Recording of Loudness Curve.
  4. Play back your project.

Result

The short-term loudness level is measured in real time at the cursor position. The corresponding loudness curve is written to the loudness track.
