loudnessranging

Loudnessranging is a technique used in audio engineering and music production to ensure that the loudness of a track remains consistent throughout its duration. This is particularly important in the streaming era, where algorithms often prioritize tracks with higher loudness levels. Loudnessranging involves dynamically adjusting the volume of a track to maintain a target loudness level, typically measured in LUFS (Loudness Units relative to Full Scale).

The process begins with analyzing the audio to determine its current loudness levels. This data is then used to create a loudness curve, which maps out the variations in loudness over time. The loudnessranger then applies adjustments to the audio to flatten this curve, ensuring that the track's loudness remains consistent. This can involve increasing the volume of quieter sections and decreasing the volume of louder sections.

Loudnessranging is often used in conjunction with other mastering techniques, such as equalization and compression. It is particularly useful for tracks that have significant dynamic range, such as those with loud intros or quiet verses. By applying loudnessranging, engineers can ensure that the track's loudness remains consistent, making it more likely to be heard by listeners and to perform well in streaming algorithms. However, it's important to note that excessive loudnessranging can lead to a loss of dynamic range and a lack of clarity in the audio. Therefore, it should be used judiciously and in conjunction with other mastering techniques.
