Loudness Meter

The Loudness meter allows you to analyze, measure, and monitor the loudness of your project in real time during playback or mixing.

  • To open the loudness meter, select the Loudness tab at the bottom of the meter display in the right zone of the Project window or the MixConsole, or in the Control Room.

Activate Control Room View

Shows/Hides the Control Room section.

Loudness meter

Shows the Integrated value as a triangle in the left meter scale and the Short-Term value as a triangle in the right meter scale.

Measure Loudness

Activates the loudness measurement.

Switch between LU and LUFS

Switches the meter scale between LUFS (absolute values) and LU (relative values).

Switch Between Program-Gated and Dialogue-Gated Loudness Measurement

Switches between program-gated (EBU R 128) and dialogue-gated (ITU-R BS.1770) loudness measurement.

Configure Loudness Settings

Allows you to specify a threshold value for the Momentary Max., the Short-Term, the Integrated, and the True Peak clipping indicators. If values above the set thresholds are detected, the corresponding indicators turn red.

You can switch the loudness meter between the EBU +9 scale and the EBU +18 scale and make settings for dialogue-gated loudness measurement.

To reset all values on playback start, activate the Reset on Start option.

Reset Loudness

Resets all loudness values.

Momentary Max.

Shows the maximum value of all momentary loudness values, based on a time window of 400 ms. The measurement is not gated.

Short-Term

Shows the maximum value of all short-term loudness values, based on a time window of 3 s. The measurement is not gated.

Integrated

Shows the average loudness, measured from start to stop. The period of measurement is shown in the Time display. The recommended value for the integrated loudness is -23 LUFS. This absolute value is the reference point for the relative LU scale, where -23 LUFS equals 0 LU.

Range

Shows the dynamic range of the audio, measured from start to stop. This value helps you to decide how much dynamic compression you can apply. The recommended range for highly dynamic audio, such as film music scores, is 20 LU.

True Peak

Shows the true peak level of the audio. The maximum permitted true peak level in production is -1 dB.

Time

Shows the duration of the integrated loudness measurement.

Dialogue

Shows the percentage of speech that is detected in the audio.

Note

This value is only available if dialogue-gated loudness measurement is activated.

You can switch the gating mode in the Loudness tab at the bottom of the meter display in the right zone of the Project window or the MixConsole, or in the Control Room.
