Which feature in AV systems is primarily used to maintain audio consistency across devices?

Volume normalization is a feature in audio-visual systems designed to ensure that audio levels remain consistent across various devices and playback scenarios. This process analyzes the audio signal and adjusts the volume to achieve a standard level, which helps to prevent sudden loud peaks or overly quiet passages that can occur when transitioning between different audio sources. This consistency is crucial in AV applications, as it enhances the listener's experience by providing a balanced audio output, regardless of the source.

By maintaining a uniform volume level, volume normalization also eliminates the need for users to frequently adjust their speakers or devices when switching from one content source to another, facilitating smoother transitions in presentations or performances. It plays a critical role in professional audio setups, where variations in volume can be distracting and may detract from the overall quality of the presentation.
