PART 1.Prelude to Audio Normalization

What is Audio Normalization

What does normalizing audiodo? From the technical perspective, to normalize audio files is to adjust the overall volume by a fixed amount to reach a target level, which can be achieved with two principal modes: peak normalization and loudness normalization.

In specific, Peak Normalization means bringing the highest PCM (digitallyrepresents sampledanalog signals) sample value or analog signal peak to a given level, say 0 dBFS, the loudest level allowed in a digital system, which is widely used to normalize audio levels via optimal use of the available dynamic range. Thus, audio leveler software comes in handy.

Loudness Normalization refers to bringing the average amplitude to a target chosen level, like the RMS value, in which ‘average power’ can be human-perceived loudness. For example, the reference level of YouTube is 14 LUFS but will be lowered to a certain level to fit a specific program. Usually, loudness normalization is born to overcome varying loudness when playing multiple songs in a sequence.

Why Normalize Audio

The reasons why people need to normalize audio files may be summarized as follows: to gain maximum volume and to match the desired volume. The former applies to the situation when you intend to adjust your quiet audio file as loud as possible without changing its dynamic range, while the latter works if you anticipate bringing a group of audio files at various volumes closer to the same volume.

Anyway, audio normalization is a fast way to adjust clip volume to its optimal listening levels without distortion. In this case, the signal-to-noise ratio and relative dynamics still remain in their original levels in spite of the constant amount of gain throughout the volume recording process. If you have an video volume normalizer ormp3 normalizer at hand, you will have chance to get quality audio for better playback whenever you want.
