What does normalizing volume do?

To normalize audio is to change its overall volume by a fixed amount to reach a target level. It is different from compression that changes volume over time in varying amounts. It does not affect dynamics like compression, and ideally does not change the sound in any way other than purely changing its volume.

Does normalize volume affect quality?

Proper normalizing does not affect the dynamic range of the audio; it simply adds or subtracts gain from the audio to make it louder or quieter, respectively.

Should I normalize to 0dB?

Normalizing help you to increase its volume proportionally right up to 0dB (-6dB to -3dB is recommended), resulting in a louder sound without changing the dynamic range of the original file.

What is normalize audio volume?

Audio normalization is the application of a constant amount of gain to an audio recording to bring the amplitude to a target level (the norm). Because the same amount of gain is applied across the entire recording, the signal-to-noise ratio and relative dynamics are unchanged.
