What does the normalize function do in an audio editing context?

The normalize function in audio editing primarily serves to automatically adjust the gain of an audio file so that its loudest peak reaches 0 dB, which is the maximum level before distortion would occur. This process does not alter the relative dynamics of the audio but ensures that the audio clip utilizes the maximum available headroom without clipping.

By setting the loudest point of the audio to 0 dB, normalizing helps in achieving a consistent overall level, making it easier to mix with other tracks or for further processing. It should be noted that normalizing does not change the dynamics of the track, as it maintains the same balance between soft and loud parts; it merely raises the overall level to maximize the potential volume without distortion.

Other options reference different functions or aspects of audio editing, such as general volume adjustments across tracks or frequency enhancements, which do not encapsulate the specific action of the normalize function.
