Non-destructive Source Normalization can be enabled at either the Parent or overridden at the child level of the Actor-Mixer Hierarchy for any sound or group of sounds. Enabling loudness normalization provides normalization of any sources by applying an automatic gain calculated from the measured loudness of the source recording.
Enabling Loudness Normalization in the Source Setting tab of a Sound Object
To hear the results of Loudness Normalization, enable Loudness Normalization in the Source Settings for Sound Objects contained within these Work Units:

Historically the practice of normalization has varied widely across different development pipelines and audio engine methodologies. Enabling Loudness Normalization as part of your mixing strategy gives you a reliable way to ensure that two sounds playing at the same volume (e.g. -10 dB) will be perceived as playing at exactly at the same level. In this way the sound content is uniformly prepared in a way that inspires confidence during mixing.

Loudness Normalization is applied to source files at a target value of -23 dB. Wwise analyzes the wave data, stores its loudness measurement proportional to its RMS value, and then at run-time, applies gain to the sound such that its loudness will be equal to -23 dB. For example, a sound turns out to have a loudness of -35 dB; at run-time, we "normalize it" by applying a gain of +12 dB. |
