Loudness Specifications

1. Target loudness normalization example

The following example is an unprocessed studio recording from Bits und so and demonstrates Loudness Normalization with various loudness targets from quiet to loud.

Unprocessed audio:

Television US (ATSC A/85), -24 LUFS (no gate):

Television Europe (EBU R128), -23 LUFS:

Similar to ReplayGain, -18 LUFS:

Mobile audio (similar to SoundCheck by Apple), -16 LUFS:

Very loud, -13 LUFS:

2. Define a maximum loudness range (MaxLRA)

You can also define other loudness parameters like true peak levels, dialog normalization, MaxLRA, MaxM, and MaxS, which might be required for platforms (Audible, Netflix, Spotify, podcasts, etc.) or broadcasters (EBU R128, ATSC A/85, radio and mobile, commercials).
In this example, we define two different maximum loudness range targets. More or less compression and amplification is applied so that the output fits into the chosen loudness range of 10 LU (wider dynamic range) and 5 LU (smaller dynamic range).
Also take a look at the processing statistics attached to the audio player for detailed loudness statistics.

Unprocessed audio:

Processed with Adaptive Leveler set to 10 LU MaxLRA: (wider dynamic range)

Processed with Adaptive Leveler set to 5 LU MaxLRA: (smaller dynamic range)
