R128Balance

R128Balance is a concept related to audio processing, specifically loudness normalization. It refers to a method designed to equalize the perceived loudness of different audio tracks, making them sound more consistent to the listener. This is particularly useful in broadcasting, streaming services, and music production where a variety of content, each with potentially different loudness levels, is presented.

The core of R128Balance lies in adhering to the EBU R128 recommendation, which is a standard for loudness measurement and control. This standard defines how to measure perceived loudness using algorithms like Integrated Loudness and True Peak. By applying R128Balance principles, audio engineers can ensure that a program segment, a commercial break, or a song does not suddenly jump in volume when transitioning to another.

The goal is to avoid the need for listeners to constantly adjust their volume controls. Instead of focusing on peak levels, which only measure the highest instantaneous amplitude, R128Balance considers the overall perceived loudness over a period of time. This leads to a more pleasant and uniform listening experience, preventing sudden loud bursts that can be jarring and quiet passages that might be missed. It has become a widely adopted practice in the audio industry.
