Equalizing Signals according to a Target Loudness

Open the signals to be equalized in a time-domain window.

  1. Click Modules | Psychoacoustics | Equalization.

  2. Check Target loudness.

  3. In the box, type a reference value.

  4. In Equalize signals, select the signals to be processed.

    You can deselect a signal by clicking on its name again.

  5. In Loudness indicator to use, select a parameter:

    • Loudness (ISO532-1) to equalize stationary and non-stationary sounds,

    • Maximum loudness to equalize non-stationary sound,

    • N5 or N10 to equalize sounds that vary slowly (statistical indicators recommended by Zwicker to estimate the overall loudness of sounds that varies slowly),

    • Loudness of impulse sounds to equalize impulse sounds,

    • Loudness (ANSI S3.4-2007) to equalize stationary sounds,

    • dB (SPL), dB(A), dB (B) or dB(C) to equalize the levels of any sounds,

    • EPNL or PNLTM to equalize aircraft sounds.

  6. Click OK.
