loudness normalization

Loudness normalization is a process that adjusts the volume of audio recordings so they sound consistently loud to the listener. Instead of just increasing or decreasing the raw volume (amplitude), it considers how humans perceive loudness, ensuring different audio tracks or segments have a similar perceived volume level. This helps prevent situations where some parts are too faint or too loud, making listening more comfortable and reducing the need for constant volume adjustments. Think of it as a way to make all audio content sound balanced and evenly loud, regardless of how they were originally recorded or produced.
