Normalization

Normalization is useful when you have audio from multiple sources and you want to adjust the volume to the same level.

Loudness Normalization adjusts the volume based on the perceived loudness of the audio file.
Peak Normalization adjusts the volume based on the highest peak in the audio file.

Loudness normalization

Normalization uses EBU R128 loudness calculation algorithm. Default value is +93 dB SPL (-14 dB LUFS) (ReplayGain Δ -4.00 dB) which is standard setting for all kind of music.

  • ReplayGain calibrated reference level 89 dB SPL equals EBU R128 -18 LUFS.
  • Sound Pressure Level 89 dB SPL is calibrated to -14 dB RMS relative to a full scaled sine wave (0 dB FS).
    • SPL calibration level 83 dB SPL equals -20 dB RMS relative to a full scaled sine wave (0 dB FS)
  • EBU R128 is calibrated to 1 kHz stereo sine wave (0 LUFS equals 0 dB FS).

Prevent clipping

Avoid signal to go beyond limits of the sampling space (0 dB FS).

Delete leading silence

Removes the silence from the beginning of the audio file.

Delete trailing silence

Removes the silence from the end of the audio file.

Digital silence (zero-samples)

Remove only digital silence that is sample values of 0's.

Threshold

Adjust the threshold value of the silence removal from -80 dB FS to -20 dB FS.

-80 dB FS being near to the digital silence (0.01 % of the 0 dB FS peak) and -20 dB FS (10 % of the 0 dB FS peak)

Fade In

Gradually increase the volume from silence at the beginning. Duration can be set to a value between 1 and 10 seconds.

Fade Out

Gradually reduce to silence at the end. Duration can be set to a value between 1 and 10 seconds.

Add leading silence

Adds specified duration of digital silence (zero-samples) to the beginning of the audio file.

Add trailing silence

Adds specified duration of digital silence (zero-samples) to the end of the audio file.
